[PATCH 0/4] mmu notifier debug annotations/checks

[Daniel Vetter]

Hi all,

Here's the respin. Changes:

- 2 patches for checking return values of callbacks dropped, they landed

- move the lockdep annotations ahead, since I think that part is less
  contentious. lockdep map now also annotates invalidate_range_end, as
  requested by Jason.

- add a patch to prime lockdep, idea from Jason, let's hear whether the
  implementation fits.

- I've stuck with the non_block_start/end for now and not switched back to
  preempt_disable/enable, but with comments as suggested by Andrew.
  Hopefully that fits the bill, otherwise I can go back again if the
  consensus is more there.

Review, comments and ideas very much welcome.

Cheers, Daniel
