>Description:
if i have a msdosfs filesystem mounted via /etc/fstab, and i try unmounting it with 'umount -a', it doesn't unmount. although devices with other filesystems unmount just fine.
>How-To-Repeat:
1. add an entry for 'msdosfs' device in /etc/fstab
2. mount it with 'mount -a'
3. unmount it with 'umount -a', it will not unmount.
