Jiang Yi 1d6ef27659 target: Fix COMPARE_AND_WRITE caw_sem leak during se_cmd quiesce ... This patch addresses a COMPARE_AND_WRITE se_device->caw_sem leak, that would be triggered during normal se_cmd shutdown or abort via __transport_wait_for_tasks(). This would occur because target_complete_cmd() would catch this early and do complete_all(&cmd->t_transport_stop_comp), but since target_complete_ok_work() or target_complete_failure_work() are never called to invoke se_cmd->transport_complete_callback(), the COMPARE_AND_WRITE specific callbacks never release caw_sem. To address this special case, go ahead and release caw_sem directly from target_complete_cmd(). (Remove '&& success' from check, to release caw_sem regardless of scsi_status - nab) Signed-off-by: Jiang Yi <jiangyilism@gmail.com> Cc: <stable@vger.kernel.org> # 3.14+ Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>		2017-07-06 23:11:32 -07:00
