in scsi_lib.c, in scsi_request_fn, near the top of the main
while (!blk_queue_plugged(q)) {
loop:
if (!scsi_dev_queue_ready(q, sdev)) {
if ((req->cmd_flags & REQ_FAILFAST) &&
!(req->cmd_flags & REQ_PREEMPT)) {
scsi_kill_request(req, q);
continue;
}
break;
}
If I remove the "if failfast and not preempt then kill" logic, my
problem goes away.
