+For efficiency, as other kernel components, memory cgroup uses some optimization
+to avoid unnecessary cacheline false sharing. usage_in_bytes is affected by the
+method and doesn't show 'exact' value of memory(and swap) usage, it's an fuzz
+value for efficient access. (Of course, when necessary, it's synchronized.)

+Netburst-based Xeon support
+---------------------------
 
-Other Xeons have chips with only one sensor.
+Some Xeon processors based on the Netburst (early Pentium 4, from 2001 to
+2003) microarchitecture had real MAX1617, ADM1021, or compatible chips
+within them, with two temperature sensors. Other Xeon processors of this

-If you have a Xeon, and the adm1021 module loads, and both temperatures

+If you have such an old Xeon, and you get two valid temperatures when
+loading the adm1021 module, then things are good.
 
-If the adm1021 module doesn't load, you should try this:
-        modprobe adm1021 force_adm1021=BUS,ADDRESS
-        ADDRESS can only be 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e.
+If nothing happens when loading the adm1021 module, and you are certain
+that your specific Xeon processor model includes compatible sensors, you
+will have to explicitly instantiate the sensor chips from user-space. See
+method 4 in Documentation/i2c/instantiating-devices. Possible slave
+addresses are 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e. It is likely that
+only temp2 will be correct and temp1 will have to be ignored.
 
-If you have dual Xeons you may have appear to have two separate
-adm1021-compatible chips, or two single-temperature sensors, at distinct
-addresses.
+Previous generations of the Xeon processor (based on Pentium II/III)
+didn't have these sensors. Next generations of Xeon processors (533 MHz
+FSB and faster) lost them, until the Core-based generation which
+introduced integrated digital thermal sensors. These are supported by
+the coretemp driver.

 * 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.
+
+
+7. Debugging
+
+Because the work functions are executed by generic worker threads
+there are a few tricks needed to shed some light on misbehaving
+workqueue users.
+
+Worker threads show up in the process list as:
+
+root      5671  0.0  0.0      0     0 ?        S    12:07   0:00 [kworker/0:1]
+root      5672  0.0  0.0      0     0 ?        S    12:07   0:00 [kworker/1:2]
+root      5673  0.0  0.0      0     0 ?        S    12:12   0:00 [kworker/0:0]
+root      5674  0.0  0.0      0     0 ?        S    12:13   0:00 [kworker/1:0]
+
+If kworkers are going crazy (using too much cpu), there are two types
+of possible problems:
+
+        1. Something beeing scheduled in rapid succession
+        2. A single work item that consumes lots of cpu cycles
+
+The first one can be tracked using tracing:
+
+        $ echo workqueue:workqueue_queue_work > /sys/kernel/debug/tracing/set_event
+        $ cat /sys/kernel/debug/tracing/trace_pipe > out.txt
+        (wait a few secs)
+        ^C
+
+If something is busy looping on work queueing, it would be dominating
+the output and the offender can be determined with the work item
+function.
+
+For the second type of problems it should be possible to just check
+the stack trace of the offending worker thread.
+
+        $ cat /proc/THE_OFFENDING_KWORKER/stack
+
+The work item's function should be trivially visible in the stack
+trace.
