Subject: [PATCH 18/20] xfs: rename the whichfork variable in xfs_buffered_write_iomap_begin
Date: Tue,  8 Oct 2019 09:15:25 +0200	[thread overview]
Message-ID: <20191008071527.29304-19-hch@lst.de> (raw)
In-Reply-To: <20191008071527.29304-1-hch@lst.de>

Renaming whichfork to allocfork in xfs_buffered_write_iomap_begin makes
the usage of this variable a little more clear.
