charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: linux-f2fs-devel-bounces@lists.sourceforge.net From: "Matthew Wilcox (Oracle)" This function now only uses the mapping argument to look up the inode, and both callers already have the inode, so just pass the inode instead of the mapping.
