When issued LUN reset under heavy i/o, we hit the qedi WARN_ON
because of a mismatch in firmware i/o cmd cleanup request count
and i/o cmd cleanup response count received. The mismatch is
because of the race caused by the postfix increment of
cmd_cleanup_cmpl.

Is the issue that cmd_cleanup_cmpl's increment is not seen by
qedi_cleanup_all_io's wait_event_interruptible_timeout call when it
wakes up, and your patch fixes this by doing a pre increment?
Does doing a pre increment give you barrier like behavior and is that
why this works? I thought if wake_up ends up waking up the other thread it
does a barrier already, so it's not clear to me how changing to a
pre-increment helps.
Is doing a pre-increment a common way to handle this? It looks like we do a
post increment and wake_up* in other places. However, like in the scsi layer
we do wake_up_process and memory-barriers.txt says that always does a general
barrier, so is that why we can do a post increment there?
Does pre-increment give you barrier like behavior, and is the wake_up call
not waking up the process so we didn't get a barrier from that, and so that's
why this works?

Yes, cmd_cleanup_cmpl's increment is not seen by qedi_cleanup_all_io's
wait_event_interruptible_timeout call when it wakes up, even after firmware
post all the ISCSI_CQE_TYPE_TASK_CLEANUP events for requested cmd_cleanup_req.
Yes, pre increment did addressed this issue. Do you feel otherwise ?

Issue happen before calling wake_up. When we gets a ISCSI_CQE_TYPE_TASK_CLEANUP surge on
multiple Rx threads, cmd_cleanup_cmpl tend to miss the increment. The scenario is more similar to
multiple threads access cmd_cleanup_cmpl causing race during postfix increment. This could be because of
thread reading the same value at a time.
Now that I am explaining it, it felt instead of pre-incrementing cmd_cleanup_cmpl,
it should be atomic variable. Do see any issue ?

Yeah, atomic.
And then I guess for this:
if (qedi_conn->cmd_cleanup_req > 0) {
QEDI_INFO(&qedi->dbg_ctx, QEDI_LOG_TID,
"Freeing tid=0x%x for cid=0x%x\n",
cqe->itid, qedi_conn->iscsi_conn_id);
qedi_conn->cmd_cleanup_cmpl++;
wake_up(&qedi_conn->wait_queue);
we might only want to do the wake_up once:
if (atomic_inc_return(&qedi_conn->cmd_cleanup_cmpl) ==
qedi_conn->cmd_cleanup_req) {
?
