[Satoru Takeuchi <takeuchi_satoru@jp.fujitsu.com>]

* actual result

   ==================================================
   # btrfs qgroup assign --no-rescan 0/260 1/261 /btrfs
   btrfs qgroup assign: unrecognized option '--no-rescan'
   usage: btrfs qgroup assign [options] <src> <dst> <path>

       Assign SRC as the child qgroup of DST

       --rescan       schedule qutoa rescan if needed
       --no-rescan

   ==================================================

* expected result

   ==================================================
   # ./btrfs qgroup assign --no-rescan 0/260 1/261 /btrfs
