Hi
No exactly sure which patch did it - but when I'm now checking 3.8-rc5 kernel,
I cannot use anymore this 'undock' command:
echo 1 >/sys/devices/platform/dock.0/undock
which works ok with 3.7 kernel - to properly undock my T61 before suspend.
Adding Davem to the list, since this looks like networking.
That said, I'm also starting to wonder if you're just triggering odd
bugs because of some use-after-free corruption of random kernel data
structures? I seem to have a dim memory of you usually doing your
trinity runs with more debugging o
Writeback implements its own worker pool - each bdi can be associated
with a worker thread which is created and destroyed dynamically. The
worker thread for the default bdi is always present and serves as the
"forker" thread which forks off worker threads for other bdis.

There are cases where userland wants to tweak the priority and
affinity of writeback flushers. Expose bdi_wq to userland by setting
WQ_SYSFS. It appears under /sys/bus/workqueue/devices/writeback/ and
allows adjusting maximum concurrency level, cpumask and nice level.

Implement a function which queries whether it currently is running off
a workqueue rescuer. This will be used to convert writeback to

Hello,
There's no reason for writeback to implement its own worker pool when
using workqueue is much simpler and more efficient. This patchset
replaces writeback's custom worker pool with unbound workqueue and
also exports it to userland using WQ_SYSFS so that it can be tuned
from userland as req
