[PATCH 20/40] workqueue: implement per-cwq active work limit
Add cwq->nr_active, cwq->max_active and cwq->delayed_work. nr_active counts the number of active works per cwq. A work is active if it's flushable (colored) and is on cwq's worklist. If nr_active reaches max_active, new works are queued on cwq->delayed_work and activated later as works on the cwq complete and de... 17 Jan 2010 20:38

[PATCH 02/40] sched: rename preempt_notifiers to sched_notifiers and refactor implementation
Rename preempt_notifiers to sched_notifiers and move it to sched.h. Also, refactor implementation in sched.c such that adding new callbacks is easier. This patch does not introduce any functional change and in fact generates the same binary at least with my configuration (x86_64 SMP, kvm and some debug options).... 17 Jan 2010 20:38

[PATCH 25/40] workqueue: make single thread workqueue shared worker pool friendly
Reimplement st (single thread) workqueue so that it's friendly to shared worker pool. It was originally implemented by confining st workqueues to use cwq of a fixed cpu and always having a worker for the cpu. This implementation isn't very friendly to shared worker pool and suboptimal in that it ends up crossing ... 17 Jan 2010 20:38
