- ->releasepage() annotated (s/int/gfp_t), instances updated - missing gfp_t in fs/* added - fixed misannotation from the original sweep caught by bitwise checks: XFS used __nocast both for gfp_t and for flags used by XFS allocator. The latter left with unsigned int __nocast; we might want to add a different type for those but for now let's leave them alone. That, BTW, is a case when __nocast use had been actively confusing - it had been used in the same code for two different and similar types, with no way to catch misuses. Switch of gfp_t to bitwise had caught that immediately... One tricky bit is left alone to be dealt with later - mapping->flags is a mix of gfp_t and error indications. Left alone for now.

Beginning of gfp_t annotations: - -Wbitwise added to CHECKFLAGS - old __bitwise renamed to __bitwise__ - __bitwise defined to either __bitwise__ or nothing, depending on __CHECK_ENDIAN__ being defined - gfp_t switched from __nocast to __bitwise__ - force cast to gfp_t added to __GFP_... constants - new helper - gfp_zone(); extracts zone bits out of gfp_t value and casts the result to int Signed-off-by:

This patch removes try_module_get race in elevator_find. try_module_get should always be called with the spinlock protecting what the module init/cleanup routines register/unregister to held. In the case of elevators, we should be holding elv_list to avoid it going away between spin_unlock_irq and try_module_get. Signed-off-by:

disk stat when "now" is different from disk->stamp. Otherwise, we are again needlessly adding zero to the stats. Signed-off-by:

struct gendisk has these two fields: stamp, stamp_idle. Update to stamp_idle is always in sync with stamp and they are always the same. Therefore, it does not add any value in having two fields tracking same timestamp. Suggest to remove it. Also, we should only update gendisk stats with non-zero value. Advantage is that we don't have to needlessly calculate memory address, and then add zero to the content. Signed-off-by:
