Can I conclude from this that the polling loop (2) from
http://www.mail-archive.com/linux-rdma@vger.kernel.org/msg04907.html
won't trigger a race on a multiprocessor when using mlx4 hardware ?

I don't think this patch is required for mlx4.
< 0means an error occurred while requesting notification
== 0means notification was requested successfully, and if
IB_CQ_REPORT_MISSED_EVENTS was passed in, then no
events were missed and it is
enhance the cq arming code to support IB_CQ_REPORT_MISSED_EVENTS
Signed-off-by: Or Gerlitz
I noted that the IB_CQ_REPORT_MISSED_EVENTS flag was added in the same cycle
with mlx4
and maybe as of this, mlx4 didn't implement the flag, which is used by IPoIB
The patch is compile tested only,
