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@ffw...
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
