For the moment, the attached patch compiles.  It will need folding into the
main patch.  I've pushed my tree out to:

	git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git

on branch init_task.

Currently, it's using the sb_mount LSM hook to check remount, but this will
need to be changed once the user interface is solidified.  THe problem is
getting the target path through to apparmor.
