Subject: [PATCH 2/5] xfs: don't iunlock unlocked inodes
Date: Fri, 12 Jan 2018 14:04:12 -0800	[thread overview]
Message-ID: <151579465207.8694.2459805113822761321.stgit@magnolia> (raw)
In-Reply-To: <151579463950.8694.320025813242574491.stgit@magnolia>

From: Darrick J. Wong <darrick.wong@oracle.com>

Don't iunlock an unlocked inode, which can happen if the parent pointer
scrubber bails out with sc->ip unlocked while trying to grab the parent
directory inode.
