[GIT PULL] xfs: fixes for 6.4-rc5

[Dave Chinner <david@fromorbit.com>]

Hi Linus,

Can you please pull the latest XFS updates fixes from the tag below?

These are a set of regression fixes discovered on recent kernels.  I
was hoping to send this to you a week and half ago, but events out
of my control delayed finalising the changes until early this week.

Whilst the diffstat looks large for this stage of the merge window,
a large chunk of it comes from moving the guts of one function from
one file to another i.e. it's the same code, it is just run in a
different context where it is safe to hold a specific lock.
Otherwise the individual changes are relatively small and straigtht
forward.

The code in the XFS branch merges cleanly with your tree as of
commit 5f63595ebd82 ("Merge tag 'input-for-v6.4-rc5' of
git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input"). Let me
know if you see something different or unexpected.

-Dave.
