Hm, I see. Yeah, none of the 'regular' filesystems have that set. Why is
that, if it's easy to explain? From a naive perspective it seems like if
you have the permissions to the device then the uid/gid mapping should
be generic (the on-disk id is the id *inside* the namespace, the kernel
maps that based on the id_map file to processes outside the namespace),
but I'm sure that's insecure in a way I'm not seeing.

Aside from the patch to build as a module, is there anything further to
be done on the loopfs side of things? If not I may try to get this
merged myself if you don't mind.
