Hi folks,

v6: https://lore.kernel.org/r/20210302024816.2525095-1-hsiangkao@redhat.com

This patchset attempts to support shrinking free space in the last AG.
This version mainly addresses previous review of v7. Hope I don't miss
previous comments...

gitweb:
https://git.kernel.org/pub/scm/linux/kernel/git/xiang/linux.git/ tags/xfs/shrink_lastag_v8

changes since v7:
 - [3/5] rename `len' to `delta' (Darrick);
 - [3/5] add agi->length vs `delta' check (Darrick);
 - [4/5] drop an necessary blank line (Darrick).
 - Also xfs_errortag_random_default has been fixed in [5/5].

Thanks for the time!

Thanks,
Gao Xiang
