The code at the end of alua_rtpg_work() is as follows: scsi_device_put(sdev); kref_put(&pg->kref, release_port_group); In other words, alua_rtpg_queue() must hold an sdev reference and a pg reference before queueing rtpg work. If no rtpg work is queued no additional references should be held when alua_rtpg_queue() returns. If no rtpg work is queued, ensure that alua_rtpg_queue() only gives up the sdev reference if that reference was obtained by the same alua_rtpg_queue() call.
