3.8.0+ #3
This happened after 'umount /btrfs' was interrupted by ctl-C
# mount | egrep btrfs
/dev/mapper/mpathe on /btrfs type btrfs (rw,degraded)
# cat /etc/mtab | egrep btrfs
/dev/mapper/mpathe /btrfs btrfs rw,degraded 0 0
# cat /proc/mounts | egrep btrfs
# umount /btrfs
umount: /btrfs: not mounted

That's because your mount still uses /etc/mtab for some reason, I thought it had
stopped doing that and was using /proc/mounts? Anyway it's just because the
entry made it into mtab, if umount and /proc/mounts says its not there then its
not there. Thanks,
Josef
