Please use tab not space for indention.
And I think we need "rm -f $tmp.*" in _cleanup() even if you don't take
use any $tmp.* files, because helper functions may use the tmp files
internally, we should remove them as well.

It could support ext2/ext3 as well, and move the test to shared
directory, as what shared/001 does.

This requires debugfs pseudo filesystem, not debugfs binary. Use
_require_command "$DEBUGFS_PROG" debugfs
But you may want to define $DEBUGFS_PROG first in common/config.

Though the bug only happens when last_orphan is set to 5, I think we can
test all reserved inode numbers, 1-10, 11 is the first non-reserved
inode.

You need a "Silence is golden" in golden image to indicate that this
test doesn't expect any output.

If you're not using big seq number on purpose, pick the smallest
available sequence number, that's 021 in this case.
