xfs: implement ->update_time
Use this new method to replace our hacky use of ->dirty_inode. An additional benefit is that we can now propagate errors up the stack. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Ben Myers <bpm@sgi.com>

- * This is called by the VFS when dirtying inode metadata. This can happen
- * for a few reasons, but we only care about timestamp updates, given that
- * we handled the rest ourselves. In theory no other calls should happen,
- * but for example generic_write_end() keeps dirtying the inode after
- * updating i_size. Thus we check that the flags are exactly I_DIRTY_SYNC,
- * and skip this call otherwise.
- *
- * We'll hopefull get a different method just for updating timestamps soon,
- * at which point this hack can go away, and maybe we'll also get real
- * error handling here.
