[GIT PULL] xfs: 4.20 merge

[Dave Chinner <david@fromorbit.com>]

Hi Linus,

Can you please pull the XFS 4.20 update from the tag listed below?
There's not a huge amount of change in this cycle - Darrick has been
out of action for a couple of months (hence me sending the last few
pull requests), so we decided a quiet cycle mainly focussed on bug
fixes was a good idea. Darrick will take the helm again at the end of
this merge window.

The branch has applied cleanly to your current tree, so you
shouldn't see any problems with it.

FYI, I may be sending another update later in the cycle - there's a
pending rework of the clone/dedupe_file_range code that fixes
numerous bugs that is spread amongst the VFS, XFS and ocfs2 code. It
has been reviewed and tested, Al and I just need to work out the
details of the merge, so it may come from him rather than me.

Thanks!

-Dave.
