umount: add --all-targets
The same source (whole filesystem or filesystems subvolume) could be
mounted on more targets (mountpoints). For example bind mounts or
btrfs sub-volumes.
If you want to detach the source device from the system then you need
to unmount all the mountpoints.
umount --all-targets <device|mountpoint>
provides this functionality. This option could be used together with
--recursive. Then all nested mountpoints within the filesystem are
unmounted too. For example:
umount --recursive --all-targets /dev/sdb1
should be a way how to make the device unmounted at all.
