From e372843a407ddff1e4c4acc7cdf3df9987bf48cc Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 19 Sep 2016 11:26:41 +1000 Subject: [PATCH] xfs: refactor xfs_setfilesize 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.
