Yes, but why are there any commands in the work_q at all? In other
words, why is this loop entered at all?
list_for_each_entry_safe(scmd, next, work_q, eh_entry) {
if (!scsi_device_online(scmd->device) ||
(!scsi_eh_try_stu(scmd) &&
!scsi_eh_tur(scmd)) ||
!scsi_eh_tur(scmd))
scsi_eh_finish_cmd(scmd, done_q);
}
srp_reconnect_target() should get rid of all queued commands already:
list_for_each_entry(req, &target->req_queue, list) {
req->scmnd->result = DID_RESET << 16;
req->scmnd->scsi_done(req->scmnd);
srp_unmap_data(req->scmnd, target, req);
}
why does the midlayer have any commands around after that loop?
- R.
