Hi folks, v6: https://lore.kernel.org/r/20210302024816.2525095-1-hsiangkao@xxxxxxxxxx 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!
