Subject: [PATCH 17/19] xfs: replace xfs_bmbt_lookup_ge with xfs_bmbt_lookup_first
Date: Mon, 18 Sep 2017 08:24:20 -0700 [thread overview]
Message-ID: <20170918152422.24345-18-hch@lst.de> (raw)
In-Reply-To: <20170918152422.24345-1-hch@lst.de>
We only use xfs_bmbt_lookup_ge to look up the first bmap record in an
inode, so replace xfs_bmbt_lookup_ge with a special purpose helper that
is a bit more descriptive.
