Hi, v5: https://lore.kernel.org/r/20210511073945.906127-1-hsiangkao@xxxxxxxxxx This adds testcases for shrinking free space in the last AG in the upstream. This version mainly addresses Darrick's previous comments mentioned in v5. changes since v5 (Darrick): - [1/3] print $errmsg when _fail; - [3/3] print $sizeb for better debugging.
