Summary:                    mount -o loop is broken again
Description: 
I see that this has been broken before and it has been fixed as well, but
im pretty darn sure the current code is b0rken.

im trying to mount an image produced by buildroot on a busybox based
system using -o loop.  It fails telling me

mount: Couldn't setup loop device.

I know its not a show-stopped, but its pretty annoying for me since i was
planning to use this as a way of providing a "firmware" update feature
(mounitng the file and reimaging the system using it as a source).  a
quick fix would be much appreciated - im about to stick gdb on it to see
what i can dig up.

if CONFIG_FEATURE_DEVFS=y, mount tries to use /dev/loop/N,
if not, it uses /dev/loopN.

This is trivially obvious if you will run strace.
