+CFQ ioscheduler tunables
+========================
+
+slice_idle
+----------
+This specifies how long CFQ should idle for next request on certain cfq queues
+(for sequential workloads) and service trees (for random workloads) before
+queue is expired and CFQ selects next queue to dispatch from.
+
+By default slice_idle is a non-zero value. That means by default we idle on
+queues/service trees. This can be very helpful on highly seeky media like
+single spindle SATA/SAS disks where we can cut down on overall number of
+seeks and see improved throughput.
+
+Setting slice_idle to 0 will remove all the idling on queues/service tree
+level and one should see an overall improved throughput on faster storage
+devices like multiple SATA/SAS disks in hardware RAID configuration. The down
+side is that isolation provided from WRITES also goes down and notion of
+IO priority becomes weaker.
+
+So depending on storage and workload, it might be useful to set slice_idle=0.
+In general I think for SATA/SAS disks and software RAID of SATA/SAS disks
+keeping slice_idle enabled should be useful. For any configurations where
+there are multiple spindles behind single LUN (Host based hardware RAID
+controller or for storage arrays), setting slice_idle=0 might end up in better
+throughput and acceptable latencies.
+
+CFQ IOPS Mode for group scheduling
+===================================
+Basic CFQ design is to provide priority based time slices. Higher priority
+process gets bigger time slice and lower priority process gets smaller time
+slice. Measuring time becomes harder if storage is fast and supports NCQ and
+it would be better to dispatch multiple requests from multiple cfq queues in
+request queue at a time. In such scenario, it is not possible to measure time
+consumed by single queue accurately.
+
+What is possible though is to measure number of requests dispatched from a
+single queue and also allow dispatch from multiple cfq queue at the same time.
+This effectively becomes the fairness in terms of IOPS (IO operations per
+second).
+
+If one sets slice_idle=0 and if storage supports NCQ, CFQ internally switches
+to IOPS mode and starts providing fairness in terms of number of requests
+dispatched. Note that this mode switching takes effect only for group
+scheduling. For non-cgroup users nothing should change.

+/sys/block/<disk>/queue/iosched/slice_idle
+------------------------------------------
+On a faster hardware CFQ can be slow, especially with sequential workload.
+This happens because CFQ idles on a single queue and single queue might not
+drive deeper request queue depths to keep the storage busy. In such scenarios
+one can try setting slice_idle=0 and that would switch CFQ to IOPS
+(IO operations per second) mode on NCQ supporting hardware.
+
+That means CFQ will not idle between cfq queues of a cfq group and hence be
+able to driver higher queue depth and achieve better throughput. That also
+means that cfq provides fairness among groups in terms of IOPS and not in
+terms of disk time.
+
+/sys/block/<disk>/queue/iosched/group_idle
+------------------------------------------
+If one disables idling on individual cfq queues and cfq service trees by
+setting slice_idle=0, group_idle kicks in. That means CFQ will still idle
+on the group in an attempt to provide fairness among groups.
+
+By default group_idle is same as slice_idle and does not do anything if
+slice_idle is enabled.
+
+One can experience an overall throughput drop if you have created multiple
+groups and put applications in that group which are not driving enough
+IO to keep disk busy. In that case set group_idle=0, and CFQ will not idle
+on individual groups and throughput should improve.

+Concurrency Managed Workqueue (cmwq)

+CONTENTS
+
+1. Introduction
+2. Why cmwq?
+3. The Design
+4. Application Programming Interface (API)
+5. Example Execution Scenarios
+6. Guidelines
+
+
+1. Introduction
+
+There are many cases where an asynchronous process execution context
+is needed and the workqueue (wq) API is the most commonly used
+mechanism for such cases.
+
+When such an asynchronous execution context is needed, a work item
+describing which function to execute is put on a queue.  An
+independent thread serves as the asynchronous execution context.  The
+queue is called workqueue and the thread is called worker.
+
+While there are work items on the workqueue the worker executes the
+functions associated with the work items one after the other.  When
+there is no work item left on the workqueue the worker becomes idle.
+When a new work item gets queued, the worker begins executing again.
+
+
+2. Why cmwq?
+
+In the original wq implementation, a multi threaded (MT) wq had one
+worker thread per CPU and a single threaded (ST) wq had one worker
+thread system-wide.  A single MT wq needed to keep around the same
+number of workers as the number of CPUs.  The kernel grew a lot of MT
+wq users over the years and with the number of CPU cores continuously
+rising, some systems saturated the default 32k PID space just booting
+up.
+
+Although MT wq wasted a lot of resource, the level of concurrency
+provided was unsatisfactory.  The limitation was common to both ST and
+MT wq albeit less severe on MT.  Each wq maintained its own separate
+worker pool.  A MT wq could provide only one execution context per CPU
+while a ST wq one for the whole system.  Work items had to compete for
+those very limited execution contexts leading to various problems
+including proneness to deadlocks around the single execution context.
+
+The tension between the provided level of concurrency and resource
+usage also forced its users to make unnecessary tradeoffs like libata
+choosing to use ST wq for polling PIOs and accepting an unnecessary
+limitation that no two polling PIOs can progress at the same time.  As
+MT wq don't provide much better concurrency, users which require
+higher level of concurrency, like async or fscache, had to implement
+their own thread pool.
+
+Concurrency Managed Workqueue (cmwq) is a reimplementation of wq with
+focus on the following goals.
+
+* Maintain compatibility with the original workqueue API.

+
+
+3. The Design
+
+In order to ease the asynchronous execution of functions a new
+abstraction, the work item, is introduced.
+
+A work item is a simple struct that holds a pointer to the function
+that is to be executed asynchronously.  Whenever a driver or subsystem
+wants a function to be executed asynchronously it has to set up a work
+item pointing to that function and queue that work item on a
+workqueue.
+
+Special purpose threads, called worker threads, execute the functions
+off of the queue, one after the other.  If no work is queued, the
+worker threads become idle.  These worker threads are managed in so
+called thread-pools.
+
+The cmwq design differentiates between the user-facing workqueues that
+subsystems and drivers queue work items on and the backend mechanism
+which manages thread-pool and processes the queued work items.
+
+The backend is called gcwq.  There is one gcwq for each possible CPU
+and one gcwq to serve work items queued on unbound workqueues.
+
+Subsystems and drivers can create and queue work items through special
+workqueue API functions as they see fit. They can influence some
+aspects of the way the work items are executed by setting flags on the
+workqueue they are putting the work item on. These flags include
+things like CPU locality, reentrancy, concurrency limits and more. To
+get a detailed overview refer to the API description of
+alloc_workqueue() below.
+
+When a work item is queued to a workqueue, the target gcwq is
+determined according to the queue parameters and workqueue attributes
+and appended on the shared worklist of the gcwq.  For example, unless
+specifically overridden, a work item of a bound workqueue will be
+queued on the worklist of exactly that gcwq that is associated to the
+CPU the issuer is running on.
+
+For any worker pool implementation, managing the concurrency level
+(how many execution contexts are active) is an important issue.  cmwq
+tries to keep the concurrency at a minimal but sufficient level.
+Minimal to save resources and sufficient in that the system is used at
+its full capacity.
+
+Each gcwq bound to an actual CPU implements concurrency management by
+hooking into the scheduler.  The gcwq is notified whenever an active
+worker wakes up or sleeps and keeps track of the number of the
+currently runnable workers.  Generally, work items are not expected to
+hog a CPU and consume many cycles.  That means maintaining just enough
+concurrency to prevent work processing from stalling should be
+optimal.  As long as there are one or more runnable workers on the
+CPU, the gcwq doesn't start execution of a new work, but, when the
+last running worker goes to sleep, it immediately schedules a new
+worker so that the CPU doesn't sit idle while there are pending work
+items.  This allows using a minimal number of workers without losing
+execution bandwidth.
+
+Keeping idle workers around doesn't cost other than the memory space
+for kthreads, so cmwq holds onto idle ones for a while before killing
+them.
+
+For an unbound wq, the above concurrency management doesn't apply and
+the gcwq for the pseudo unbound CPU tries to start executing all work
+items as soon as possible.  The responsibility of regulating
+concurrency level is on the users.  There is also a flag to mark a
+bound wq to ignore the concurrency management.  Please refer to the
+API section for details.
+
+Forward progress guarantee relies on that workers can be created when
+more execution contexts are necessary, which in turn is guaranteed
+through the use of rescue workers.  All work items which might be used
+on code paths that handle memory reclaim are required to be queued on
+wq's that have a rescue-worker reserved for execution under memory
+pressure.  Else it is possible that the thread-pool deadlocks waiting
+for execution contexts to free up.
+
+
+4. Application Programming Interface (API)
+
+alloc_workqueue() allocates a wq.  The original create_*workqueue()
+functions are deprecated and scheduled for removal.  alloc_workqueue()
+takes three arguments - @name, @flags and @max_active.  @name is the
+name of the wq and also used as the name of the rescuer thread if
+there is one.
+
+A wq no longer manages execution resources but serves as a domain for
+forward progress guarantee, flush and work item attributes.  @flags
+and @max_active control how work items are assigned execution
+resources, scheduled and executed.
+
+@flags:
+
+  WQ_NON_REENTRANT
+
+        By default, a wq guarantees non-reentrance only on the same
+        CPU.  A work item may not be executed concurrently on the same
+        CPU by multiple workers but is allowed to be executed
+        concurrently on multiple CPUs.  This flag makes sure
+        non-reentrance is enforced across all CPUs.  Work items queued
+        to a non-reentrant wq are guaranteed to be executed by at most
+        one worker system-wide at any given time.
+
+  WQ_UNBOUND
+
+        Work items queued to an unbound wq are served by a special
+        gcwq which hosts workers which are not bound to any specific
+        CPU.  This makes the wq behave as a simple execution context
+        provider without concurrency management.  The unbound gcwq
+        tries to start execution of work items as soon as possible.
+        Unbound wq sacrifices locality but is useful for the following
+        cases.
+
+        * Wide fluctuation in the concurrency level requirement is
+          expected and using bound wq may end up creating large number
+          of mostly unused workers across different CPUs as the issuer
+          hops through different CPUs.
+
+        * Long running CPU intensive workloads which can be better
+          managed by the system scheduler.
+
+  WQ_FREEZEABLE
+
+        A freezeable wq participates in the freeze phase of the system
+        suspend operations.  Work items on the wq are drained and no
+        new work item starts execution until thawed.
+
+  WQ_RESCUER
+
+        All wq which might be used in the memory reclaim paths _MUST_
+        have this flag set.  This reserves one worker exclusively for
+        the execution of this wq under memory pressure.
+
+  WQ_HIGHPRI
+
+        Work items of a highpri wq are queued at the head of the
+        worklist of the target gcwq and start execution regardless of
+        the current concurrency level.  In other words, highpri work
+        items will always start execution as soon as execution
+        resource is available.
+
+        Ordering among highpri work items is preserved - a highpri
+        work item queued after another highpri work item will start
+        execution after the earlier highpri work item starts.
+
+        Although highpri work items are not held back by other
+        runnable work items, they still contribute to the concurrency
+        level.  Highpri work items in runnable state will prevent
+        non-highpri work items from starting execution.
+
+        This flag is meaningless for unbound wq.
+
+  WQ_CPU_INTENSIVE
+
+        Work items of a CPU intensive wq do not contribute to the
+        concurrency level.  In other words, runnable CPU intensive
+        work items will not prevent other work items from starting
+        execution.  This is useful for bound work items which are
+        expected to hog CPU cycles so that their execution is
+        regulated by the system scheduler.
+
+        Although CPU intensive work items don't contribute to the
+        concurrency level, start of their executions is still
+        regulated by the concurrency management and runnable
+        non-CPU-intensive work items can delay execution of CPU
+        intensive work items.
+
+        This flag is meaningless for unbound wq.
+
+  WQ_HIGHPRI | WQ_CPU_INTENSIVE
+
+        This combination makes the wq avoid interaction with
+        concurrency management completely and behave as a simple
+        per-CPU execution context provider.  Work items queued on a
+        highpri CPU-intensive wq start execution as soon as resources
+        are available and don't affect execution of other work items.
+
+@max_active:
+
+@max_active determines the maximum number of execution contexts per
+CPU which can be assigned to the work items of a wq.  For example,
+with @max_active of 16, at most 16 work items of the wq can be
+executing at the same time per CPU.
+
+Currently, for a bound wq, the maximum limit for @max_active is 512
+and the default value used when 0 is specified is 256.  For an unbound
+wq, the limit is higher of 512 and 4 * num_possible_cpus().  These
+values are chosen sufficiently high such that they are not the
+limiting factor while providing protection in runaway cases.
+
+The number of active work items of a wq is usually regulated by the
+users of the wq, more specifically, by how many work items the users
+may queue at the same time.  Unless there is a specific need for
+throttling the number of active work items, specifying '0' is
+recommended.
+
+Some users depend on the strict execution ordering of ST wq.  The
+combination of @max_active of 1 and WQ_UNBOUND is used to achieve this
+behavior.  Work items on such wq are always queued to the unbound gcwq
+and only one work item can be active at any given time thus achieving
+the same ordering property as ST wq.
+
+
+5. Example Execution Scenarios
+
+The following example execution scenarios try to illustrate how cmwq
+behave under different configurations.
+
+ Work items w0, w1, w2 are queued to a bound wq q0 on the same CPU.
+ w0 burns CPU for 5ms then sleeps for 10ms then burns CPU for 5ms
+ again before finishing.  w1 and w2 burn CPU for 5ms then sleep for
+ 10ms.
+
+Ignoring all other tasks, works and processing overhead, and assuming
+simple FIFO scheduling, the following is one highly simplified version
+of possible sequences of events with the original wq.
+
+ TIME IN MSECS  EVENT
+ 0              w0 starts and burns CPU
+ 5              w0 sleeps
+ 15             w0 wakes up and burns CPU
+ 20             w0 finishes
+ 20             w1 starts and burns CPU
+ 25             w1 sleeps
+ 35             w1 wakes up and finishes
+ 35             w2 starts and burns CPU
+ 40             w2 sleeps
+ 50             w2 wakes up and finishes
+
+And with cmwq with @max_active >= 3,
+
+ TIME IN MSECS  EVENT
+ 0              w0 starts and burns CPU
+ 5              w0 sleeps
+ 5              w1 starts and burns CPU
+ 10             w1 sleeps
+ 10             w2 starts and burns CPU
+ 15             w2 sleeps
+ 15             w0 wakes up and burns CPU
+ 20             w0 finishes
+ 20             w1 wakes up and finishes
+ 25             w2 wakes up and finishes
+
+If @max_active == 2,
+
+ TIME IN MSECS  EVENT
+ 0              w0 starts and burns CPU
+ 5              w0 sleeps
+ 5              w1 starts and burns CPU
+ 10             w1 sleeps
+ 15             w0 wakes up and burns CPU
+ 20             w0 finishes
+ 20             w1 wakes up and finishes
+ 20             w2 starts and burns CPU
+ 25             w2 sleeps
+ 35             w2 wakes up and finishes
+
+Now, let's assume w1 and w2 are queued to a different wq q1 which has
+WQ_HIGHPRI set,
+
+ TIME IN MSECS  EVENT
+ 0              w1 and w2 start and burn CPU
+ 5              w1 sleeps
+ 10             w2 sleeps
+ 10             w0 starts and burns CPU
+ 15             w0 sleeps
+ 15             w1 wakes up and finishes
+ 20             w2 wakes up and finishes
+ 25             w0 wakes up and burns CPU
+ 30             w0 finishes
+
+If q1 has WQ_CPU_INTENSIVE set,
+
+ TIME IN MSECS  EVENT
+ 0              w0 starts and burns CPU
+ 5              w0 sleeps
+ 5              w1 and w2 start and burn CPU
+ 10             w1 sleeps
+ 15             w2 sleeps
+ 15             w0 wakes up and burns CPU
+ 20             w0 finishes
+ 20             w1 wakes up and finishes
+ 25             w2 wakes up and finishes
+
+
+6. Guidelines
+
+* Do not forget to use WQ_RESCUER if a wq may process work items which
+  are used during memory reclaim.  Each wq with WQ_RESCUER set has one
+  rescuer thread reserved for it.  If there is dependency among
+  multiple work items used during memory reclaim, they should be
+  queued to separate wq each with WQ_RESCUER.
+
+* Unless strict ordering is required, there is no need to use ST wq.
+
+* Unless there is a specific need, using 0 for @max_active is
+  recommended.  In most use cases, concurrency level usually stays
+  well under the default limit.
+
+* A wq serves as a domain for forward progress guarantee (WQ_RESCUER),
+  flush and work item attributes.  Work items which are not involved
+  in memory reclaim and don't need to be flushed as a part of a group
+  of work items, and don't require any special attribute, can use one
+  of the system wq.  There is no difference in execution
+  characteristics between using a dedicated wq and a system wq.
+
+* Unless work items are expected to consume a huge amount of CPU
+  cycles, using a bound wq is usually beneficial due to the increased
+  level of locality in wq operations and work item execution.

-* Description:  The block table stores bad block info, including MDF+
-*               blocks gone bad over the ages. Therefore, if we have a
-*               block table in place, then use it to scan for bad blocks
-*               If not, then scan for MDF.
-*               Now, a block table will only be found if spectra was already
-*               being used. For a fresh flash, we'll go thru scanning for
-*               MDF. If spectra was being used, then there is a chance that
-*               the MDF has been corrupted. Spectra avoids writing to the
-*               first 2 bytes of the spare area to all pages in a block. This
-*               covers all known flash devices. However, since flash
-*               manufacturers have no standard of where the MDF is stored,
-*               this cannot guarantee that the MDF is protected for future
-*               devices too. The initial scanning for the block table assures
-*               this. It is ok even if the block table is outdated, as all
-*               we're looking for are bad block markers.
-*               Use this when mounting a file system or starting a
-*               new flash.
