Next round. Changes:
- I kept the two lockdep annotations patches since when I rebased this
before retesting linux-next didn't yet have them. Otherwise unchanged
except for a trivial conflict.
- Ack from Peter Z. on the kernel.h patch.
- Added annotations for non_block to invalidate_range_end. I can't test
that readily since i915 doesn't use it.
- Added might_sleep annotations to also make sure the mm side keeps up
it's side of the contract here around what's allowed and what's not.
Comments, feedback, review as usual very much appreciated.
Daniel Vetter (5):
mm, notifier: Add a lockdep map for invalidate_range_start/end
mm, notifier: Prime lockdep
kernel.h: Add non_block_start/end()
mm, notifier: Catch sleeping/blocking for !blockable
mm, notifier: annotate with might_sleep()
