From eef2380c187890816b73b1a4cb89a09203759469 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 4 Jun 2010 11:30:01 +0200 Subject: default to simple_setattr With the new truncate sequence every filesystem that wants to support file size changes on disk needs to implement its own ->setattr. So instead of calling inode_setattr which supports size changes call into a simple method that doesn't support this. simple_setattr is almost what we want except that it does not mark the inode dirty after changes. Given that marking the inode dirty is a no-op for the simple in-memory filesystems that use simple_setattr currently just add the mark_inode_dirty call. Also add a WARN_ON for the presence of a truncate method to simple_setattr to catch new instances of it during the transition period.
