Hello,

On 05/06/2010 08:28 AM, Ingo Molnar wrote:

I mostly agree on other points but TPs and sched_notifiers are
inherently different in how they are enabled/disabled.
sched_notifiers are enabled/disabled per-task and at least w/ cmwq,
there will always be some tasks with active sched_notifiers so code
level optimizations aren't really useful.

Thanks.
