ending it to the reverse-sorted
s_dirty list, to preserve the reverse-time-ordering.

This patch does the latter: if this inode was dirtied less recently than the
tail inode then copy the tail inode's timestamp into this inode.

This means that in rare circumstances, some inodes will be writen back later
than they should have been.  But the time slip will be small.
