Subject: [PATCH] xfs_check: fix test for too-high level in v2 dir node
Date: Thu, 12 Sep 2013 16:00:23 -0500 [thread overview]
Message-ID: <52322B67.80305@redhat.com> (raw)
The test as it stands allows level == XFS_DA_NODE_MAXDEPTH (5),
but a max depth of 5 equates to level values of 0 through 4.
Level 5 would be a depth of 6.
