Unlike ext4 we don't bother supporting the file system parsed text option as MS_LAZYTIME has been supported by util-linux for a long time now. The first patch is needed to make sure XFS actually sees that a dirty inode was dirtied due to lazy time, which is important for XFS as we don't otherwise use the VFS inode dirty tracking for metadata. Changes since V1: - fix i_version logging in xfs_vn_update_time, - document the racy I_DIRTY_TIME check
