The loop_scandir() expects all the files in /dev/loop/ to be actual
devices and not symlinks to devices. However, udev by default sets up
symlinks in /dev/loop/ thereby breaking the fallback scan logic when
looking for devices more than the default number of 8.
Simple way to reproduce is:
- <detach all devices>
- cd /dev/loop
- rm -f [2-7]
- losetup 0 autogen.sh
- mv 1 8
- for n in {1..7} ; do ln -s 0 $n ; done
- losetup -f
<error but should have found /dev/loop/8>
