umount: umount -r segfault
umount(8) segfaults when update incomplete mtab file after remount to
read-only (-r). For example autofs does not store info about
mountpoint to /etc/mtab file.
# mount /dev/sda1 /mnt/test
# sed -i -e 's:/dev/sda1 .*::g' /etc/mtab
# cd /mnt/test
# umount -r /mnt/test
umount: /mnt/test busy - remounted read-only
Segmentation fault
The command "umount -r" should not care about /etc/mtab if the related
mtab entry does not exist.
