Subject: [PATCH 09/12] xfs: refactor xfs_setfilesize
Date: Fri, 16 Sep 2016 13:27:11 +0200	[thread overview]
Message-ID: <1474025234-13804-10-git-send-email-hch@lst.de> (raw)
In-Reply-To: <1474025234-13804-1-git-send-email-hch@lst.de>

Rename the current function to __xfs_setfilesize and add a non-static
wrapper that also takes care of creating the transaction.  This new
helper will be used by the new iomap-based DAX path.

Signed-off-by: Christoph Hellwig <hch@lst.de>
