[PATCH 0/6] xfs: stable fixes for v4.19.y - circa v4.19.60

[Luis Chamberlain <mcgrof@kernel.org>]

Sasha,

you merged my last set of XFS fixes. I asked for one patch to not be
merged yet as one issue was not yet properly fixed. After some further
review I have identified commits which do fix the kernel crash reported
on kz#204223 [0] with generic/388, this patch set applies on top of the
last one I sent you.

These commits do quite a bit of code refactoring, and the actual fix
lies hidden in the last commit by Darrick. Due to the amount of changes
trying to extract the fix is riskier than just carring the code
refactoring. If we're OK with the code refactor for stable, its my
recommendation we keep the changes to match more with upstream and
benefit from other fixes. The code refactoring was merged on v4.20 and
Darrick's fix is the only fix upstream since the code was merged.

If others disagree with this approach please speak up.

I've run a full set of fstests against the following sections 12 times and
have found no regressions against the baseline:

xfs
xfs_logdev
xfs_nocrc_512
xfs_nocrc
xfs_realtimedev
xfs_reflink_1024
xfs_reflink_dev

Review from others is appreciated.
