Subject: [PATCH 17/19] xfs: rename the whichfork variable in xfs_buffered_write_iomap_begin
Date: Mon, 9 Sep 2019 20:27:20 +0200 [thread overview]
Message-ID: <20190909182722.16783-18-hch@lst.de> (raw)
In-Reply-To: <20190909182722.16783-1-hch@lst.de>
Renaming whichfork to allocfork in xfs_buffered_write_iomap_begin makes
the usage of this variable a little more clear.
