[PATCH 0/3] mmu_notifier fs fs_reclaim lockdep annotations

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I've finally gotten around to polish of my lockdep anntotation patches
from a while ago:

https://lore.kernel.org/dri-devel/20200610194101.1668038-1-daniel.vetter@xxxxxxxx/

That patch has been in -mm for a few days already, but it immediately hit
some issues with xfs.

Changes since v2:
- Now hopefully the bug that bombed xfs fixed.
- With unit-tests (that's the part I really wanted and never got to)
- might_alloc() helper thrown in for good.

The unit test stuff was the major drag until I figured out how to make
this very easy with the locking selftests.

Comments, review, testing all very much welcome.

Cheers, Daniel
