[PATCH v7 07/13] xfs: have xfs_vn_update_time gets its own timestamp

[Jeff Layton]

In later patches we're going to drop the "now" parameter from the
update_time operation. Prepare XFS for this by reworking how it fetches
timestamps and sets them in the inode. Ensure that we update the ctime
even if only S_MTIME is set.
