One way this could be solved is to allow opting into an alternative
path resolution mode.

E.g.
openat(AT_FDCWD, "foo/bar//mnt/info", O_RDONLY | O_ALT);

Yes, the implementation might be somewhat tricky, but that's another
question. Also I'm pretty sure that we should be reducing the
POSIX-ness of anything below "//" to the bare minimum. No seeking,
etc....

I think this would open up some nice possibilities beyond the fsinfo thing.

Thanks,
Miklos
