I was wondering about the truncate case.  Even if the DS needs to be
able to enforce the new size it seems pointless to keep a layout beyond the
size around.

I don't really see a need to drop on a chown for the blocklayout or
objlayout drivers either, given that these semantics are enforced at a higher
level.
