Subject: [PATCH 01/10] xfs: clean up iunlink functions
Date: Mon, 04 Feb 2019 09:59:03 -0800	[thread overview]
Message-ID: <154930314303.31814.5572163514956583050.stgit@magnolia> (raw)
In-Reply-To: <154930313674.31814.17994684613232167921.stgit@magnolia>

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

Fix some indentation issues with the iunlink functions and reorganize
the tops of the functions to be identical.  No functional changes.
