[PATCH 0/7] Lazy workqueues v2

From: Jens Axboe
Date: Mon Aug 24 2009 - 03:57:15 EST


This is version #2 of the lazy workqueue patchset. Changes since
the initial (v1) posting:

- Attempt to close a few of the races with exiting threads. I have
not completely audited it yet, but it should be a lot better now
at least.

- Fix a bug with wq barrier work not setting CPU correctly.

- Fix a bug with remote work sometimes being completed on both the
local and remote workqueue thread.

- Fix a compile error introduced with LOCKDEP enabled.

- Make the sleep schedule timeout be 1 jiffy longer than the lazy
exit interval, otherwise we would be going through two sleep cycles
without doing anything before the thread would be deemed OK to exit.

- One more conversion to lazy workqueues (bio-integrity).

Patches are against 2.6.31-rc7.
