[openib-general] [PATCH/RFC 1/2] IB: Return "maybe_missed_event" hint from ib_req_notify_cq()

[Shirley Ma]

Roland,

I have applied this patch and updated patch 2/2. You will send out an
updated patch 2/2, I think.
I did some extra modification in ipoib code, (which has more extra
repolls). I do see around 10% or more performance improvement now with this
change on both scaling and none scaling code. I will run oprofile tomorrow
to see the difference. I think with these extra repolls, the cpu
utilization would be much higher.

Thanks
