Subject[PATCH v2 for-next 0/4] optimise sbitmap deferred clear
Date
sbitmap takes away some cycles for my tag-deficient test, removal of
locking in sbitmap_deferred_clear() gives +~1% throuhput.

[1/4] and [4/4] are simple, it'd be great if someone could double
check for ordering issues for other two patches.

v2: add 3rd (CAS -> atomic and) and 4th patches

Pavel Begunkov (4):
sbitmap: optimise sbitmap_deferred_clear()
sbitmap: remove swap_lock
sbitmap: replace CAS with atomic and
sbitmap: simplify wrap check
