This test failed post-test fs check as well

"sb_fdblocks 3912360, counted 3912522"

Seems like it's a known bug?

Seems this is not needed.

We usually get isize from the output of _filter_mkfs, e.g.

_scratch_mkfs | _filter_mkfs 2>$tmp.mkfs >/dev/null
. $tmp.mkfs

Then all mkfs info is set accordingly, including $isize

But in this test, isize is got but not used. Remove the line?

This test failed too, is this expected (again, tested with your
djwong-experimental branck kernel and xfsprogs)?

_supported_fs xfs

> +_require_xfs_scratch_rmapbt

_require_xfs_io_command commands used in this test? e.g. falloc, fpunch, fcollapse and finsert

And '_require_command "$XFS_DB_PROG" "xfs_db"'

This is already fixed in upstream, not needed.
