Subject: [PATCH 6/6] xfs_scrub: fix weirdness in directory name check code
Date: Mon, 08 Feb 2021 20:11:49 -0800 [thread overview]
Message-ID: <161284390991.3058224.12921304382202456726.stgit@magnolia> (raw)
In-Reply-To: <161284387610.3058224.6236053293202575597.stgit@magnolia>
From: Darrick J. Wong <djwong@kernel.org>
Remove the redundant second check of fd and ISDIR in check_inode_names,
and rework the comment to describe why we can't run phase 5 if we found
other corruptions in the filesystem.
