Hi,

Sorry for little delay (yet since xfsprogs side isn't merged, and no
major changes compared with the previous version...)

This version matches
kernel: for-next
xfsprogs: https://lore.kernel.org/r/20210326024631.12921-1-hsiangkao@aol.com

and mainly addresses comments for the previous version (but note I don't
tend to dump shrink information but rather confirm the final state runtimely,
since blocksize needs to be fixed and output could change by time, so just
need to confirm xfs_repair can pass and final dblocks is what we want.)

Thanks,
Gao Xinag

changes since RFC v3 (Eryu):
 - [1/3] rename to _require_xfs_scratch_shrink;
 - [1/3] add growfs command check;
 - [1/3] try to shrink 1 dblock to check kernel support instead;
 - [2/3] use _check_scratch_fs instead;
 - [2/3] add comment on why agcount=3;
 - [2/3] add shrinkfs group;
 - [3/3] use _scratch_mount;
 - [3/3] Declare variables in stress_scratch() as local;
 - [3/3] run stress_scratch() in background;

Gao Xiang (3):
  common/xfs: add _require_xfs_scratch_shrink helper
  xfs: basic functionality test for shrinking free space in the last AG
  xfs: stress test for shrinking free space in the last AG

ping. This fstests patchset is still valid (I've confirmed with new
kernels / old kernels and old xfsprogs) and
shrinking tail AG functionality has been merged in kernel and xfsprogs.

Thanks,
Gao Xiang
