Try to trace the path from their roots to absolute root(s)... They simply
should not be in the output - that's a debugging stuff and I have no
problems with removing it from /proc/mounts. No heuristics needed - we
can pass NULL as dev_name in kern_mount() and check for NULL ->mnt_devname
in get_filesystem_info(). I'll do that as soon as threading patches will
be over (hopefully RSN - they went to Linus).
