* headers: smp_lock.h reduxAlexey Dobriyan2009-07-12
| | | | | | | | | | | | | * Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * osdblk: Adjust queue limits to lower device's limitsBoaz Harrosh2009-06-24
| | | | | | | | | | | | | | | | | | | | | | | | call blk_queue_stack_limits() to copy queue limits from the underline osd scsi_device. This is absolutely needed because osdblk cannot sleep when allocating a lower-request and therefore cannot be bouncing. TODO: Dynamic changes of limits to the lower device queue will not reflect in the upper driver Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
| * osdblk: a Linux block device for OSD objectsJeff Garzik2009-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Submitted driver exports a block device of the form /dev/osdblkX, where X is a decimal number. It does that by mounting a stacking block device on top of an osd object. For example, if you create a 2G object on an OSD device, you can then use this module to present that 2G object as a Linux block device. See inside patch for exact documentation.

* | cciss: Ignore stale commands after rebootHannes Reinecke2009-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When doing an unexpected shutdown like kexec the cciss firmware might still have some commands in flight, which it is trying to complete. The driver is doing it's best on resetting the HBA, but sadly there's a firmware issue causing the firmware _not_ to abort or drop old commands. So the firmware will send us commands which we haven't accounted for, causing the driver to panic. With this patch we're just ignoring these commands as there is nothing we could be doing with them anyway.

| * | cciss: Remove no longer needed sendcmd reject processing codescameron@beardog.cca.cpqcorp.net2009-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the cciss SCSI error handling routines operate with interrupts enabled, we no longer need to maintain the list of command completions that sendcmd() might inadvertantly scoop up, since now it only runs at driver init time, and there won't be any other commands for it to scoop up. So we can remove that list and the code that adds to it and processes it. Signed-off-by: Stephen M. Cameron <scameron@beardog.cca.cpqcorp.net> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

| * | cciss: separate error processing and command retrying code in ↵scameron@beardog.cca.cpqcorp.net2009-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sendcmd_withirq_core() Separate the error processing from sendcmd_withirq_core from the code which retries commands. The rationale for this is that the SCSI error handling code can then be made to use sendcmd_withirq_core, but avoid retrying commands. Signed-off-by: Stephen M.

| * | cciss: add cciss driver sysfs entriesAndrew Patterson2009-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add sysfs entries to the cciss driver needed for the dm/multipath tools. A file for vendor, model, rev, and unique_id is added for each logical drive under directory /sys/bus/pci/devices/<dev>/ccissX/cXdY. Where X = the controller (or host) number and Y is the logical drive number. A link from /sys/bus/pci/devices/<dev>/ccissX/cXdY/block:cciss!cXdY to /sys/block/cciss!cXdY/device is also created. A bus is created in /sys/bus/cciss. A link is created from the pci ccissX entry to /sys/bus/cciss/devices/ccissX. Please consider this for inclusion.
