[PATCH] uml ubd: handle readonly status
Use the set_disk_ro() API when the backing file is read-only, to mark the disk
read-only, during the ->open(). The current hack does not work when doing a
mount -o remount.
Also, mark explicitly the code paths which should no more be triggerable (I've
removed the WARN_ON(1) things). They should actually become BUG()s probably
but I'll avoid that since I'm not so sure the change works so well. I gave it
only some limited testing.
