Subject: [PATCH 0/2] xfs: fix mount vs shrinker race
Date: Tue, 20 Mar 2018 16:00:19 +1100	[thread overview]
Message-ID: <20180320050021.982-1-david@fromorbit.com> (raw)

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.
