Subject[GIT PULL] xfs: fixes for 5.13-rc4
Hi Linus,

Please pull this branch containing bug fixes for 5.13-rc4. This week's
pile mitigates some decades-old problems in how extent size hints
interact with realtime volumes, fixes some failures in online shrink,
and fixes a problem where directory and symlink shrinking on extremely
fragmented filesystems could fail.

The most user-notable change here is to point users at our (new) IRC
channel on OFTC. Freedom isn't free, it costs folks like you and me;
and if you don't kowtow, they'll expel everyone and take over your
channel. (Ok, ok, that didn't fit the song lyrics...)

The branch merges cleanly against upstream as of a few minutes ago.
Please let me know if anything else strange happens during the merge


The following changes since commit e3c2b047475b52739bcf178a9e95176c42bbcf8f:

xfs: bunmapi has unnecessary AG lock ordering issues (2021-05-27 08:11:24 -0700)

Fixes for 5.13-rc4:
- Fix a bug where unmapping operations end earlier than expected, which
can cause chaos on multi-block directory and symlink shrink
- Fix an erroneous assert that can trigger if we try to transition a
bmap structure from btree format to extents format with zero extents.
This was exposed by xfs/538.

Darrick J. Wong (4):
xfs: check free AG space when making per-AG reservations
xfs: standardize extent size hint validation
xfs: validate extsz hints against rt extent size when rtinherit is set
xfs: add new IRC channel to MAINTAINERS

Dave Chinner (2):
xfs: btree format inode forks can have zero extents
xfs: bunmapi has unnecessary AG lock ordering issues
