From 870f481793b585323fbda3e87c54efc116f46351 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 9 Jan 2006 20:52:01 -0800 Subject: [PATCH] replace inode_update_time with file_update_time To allow various options to work per-mount instead of per-sb we need a struct vfsmount when updating ctime and mtime. This preparation patch replaces the inode_update_time routine with a file_update_atime routine so we can easily get at the vfsmount. (and the file makes more sense in this context anyway). Also get rid of the unused second argument - we always want to update the ctime when calling this routine.
