Subject: [PATCH 11/21] xfs: rename the offset variable in xfs_writepage_map
Date: Thu, 31 May 2018 20:07:49 +0200 [thread overview]
Message-ID: <20180531180759.21631-12-hch@lst.de> (raw)
In-Reply-To: <20180531180759.21631-1-hch@lst.de>
Calling it file_offset makes the usage more clear, especially with
a new poffset variable that will be added soon for the offset inside
the page.
