Cover letter [PATCH 0/2] xfs: fix mount vs shrinker race

Hi folks,

These two patches exercise and fix a mount vs shrinker race that can result in an oops. The first patch adds a delay after sufficient superblock state has been set up to allow the VFS superblock shrinker to run, but not enough XFS state for the shrinker to run without crashing. The second patch fixes the problem.

Thoughts, comments?

Cheers,

Dave.
