Hmmm... Dmitry just showed me the new kernel sources and this interface seems
to have changed since I first looked at it. Could you try to apply this patch
and see if it helps:

fsfreeze most probably just uses the same ioctl interface we're using
directly, so there wouldn't be any difference in functionality, only more
complicated code.
