[PATCH 0/9] xfs: stable fixes for v4.19.y - circa ~ v4.19.58

[Luis Chamberlain <mcgrof@kernel.org>]

"Oyez Oyez..." its time for a stable update of fixes for XFS. 4 out of the
9 fixes here were recommended by Amir, and tested by both Amir and Sasha.
I've found a few other fixes, and have tested all these changes with
fstests against the following configurations in fstests sections as per
oscheck [0] and found no regressions in comparsin to v4.19.58 and by
running the full set of tests 3 times completely:

  * xfs
  * xfs_nocrc
  * xfs_nocrc_512
  * xfs_reflink
  * xfs_reflink_1024
  * xfs_logdev
  * xfs_realtimedev

Known issues are listed on the expunges files, but its no different than
the current baseline.

Worth noting is a now known generic/388 crash on xfs_nocrc, xfs_reflink,
and what may be a new section we should consider to track:
"xfs_reflink_normapbt" with the following resulting filesystem:

# xfs_info /dev/loop5
meta-data=/dev/loop5             isize=512    agcount=4, agsize=1310720 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=1        finobt=1, sparse=1, rmapbt=0
         =                       reflink=1
data     =                       bsize=4096   blocks=5242880, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0, ftype=1
log      =internal log           bsize=4096   blocks=2560, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

Do we want to create a baseline and track this configuration for stable
as well?

There is a stable bug tracking this, kz#204223 [1], and a respective bug
also present on upstream via kz#204049 [2] which Zorro reported. But,
again, nothing changes from the baseline.

I'd appreciate further reviews from the patches.

I have some other fixes in mind as well, but I'd rather not delay this
set and think this is a first good batch.

This also goes out as the first set of stable fixes using oscheck's
new devops infrastructure built on ansible / vagrant / terraform [3].
For this release I've used vagrant with KVM, perhaps the next one
I'll try terraform on whatever cloud solution someone is willing
to let me use.

You can also find these changes on my 20190718-linux-xfs-4.19.y-v1
branch on kernel.org [4].

Lemme know if you see any issues or have any questions.
