Hi,
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.
