   8 commit 26fd12209c08fe947be1828896ef4ffc5bd0e6df upstream.
   9
  10 list_move_tail(&schan->queued, &schan->active) makes the list_empty(schan->queued)
  11 undefined, we either should change it to:
  12 list_move_tail(schan->queued.next, &schan->active)
  13 or
  14 list_move_tail(&sdesc->node, &schan->active)
