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. -- Jens Axboe
