I'm all for reducing the need for stackable f/s such as ecryptfs from having
to remember to manage the write counts.  A stackable filesystem has to
emulate some parts of the VFS when it calls into a lower f/s: in that case,
having useful VFS helpers that do as much of the work as possible, saves a
lot of hassle.
