GFS2: Use ->dirty_inode()
The aim of this patch is to use the newly enhanced ->dirty_inode() super block operation to deal with atime updates, rather than piggy backing that code into ->write_inode() as is currently done. The net result is a simplification of the code in various places and a reduction of the number of gfs2_dinode_out() calls since this is now implied by ->dirty_inode(). Some of the mark_inode_dirty() calls have been moved under glocks in order to take advantage of then being able to avoid locking in ->dirty_inode() when we already have suitable locks. One consequence is that generic_write_end() now correctly deals with file size updates, so that we do not need a separate check for that afterwards. This also, indirectly, means that fdatasync should work correctly on GFS2 - the current code always syncs the metadata whether it needs to or not. Has survived testing with postmark (with and without atime) and also fsx. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
