Hi,
Optimizing the preempt_count operations (PREEMPT_ACTIVE + preempt_disable()) in a single operation from __schedule() callers was an idea of Linus a few month ago. Here is a re-iteration, with a few header cleanups along the way.
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git sched/preempt
HEAD: c8bda0e6afc163e7e2804d30b9e4301652dc679c
Thanks, Frederic ---
Frederic Weisbecker (7): preempt: Merge preempt_mask.h into preempt.h preempt: Rearrange a few symbols after headers merge preempt: Rename PREEMPT_CHECK_OFFSET to PREEMPT_DISABLE_OFFSET preempt: Disable preemption from preempt_schedule*() callers sched: Pull preemption disablement duty up to __schedule() callers preempt: Fix out of date comment preempt: Remove PREEMPT_ACTIVE unmasking off in_atomic()
