Hi,
I have a question about atomic operations.
According to IB specification o10-48, all atomic operation request made to
the same HCA, referencing the same physical memory are serialized with respect
to each other. I know this should be complied with if HCA supports atomic
operations,

All look fine... I rolled them up into the patch adding iw_cxgb4 (might
as well have the initial driver merge have all know fixes).

Hey Roland,
Do you have thoughts on this change? It is useful along with the
IBV_QPT_RAW_ETY type added to libibverbs for cxgb devices too.

As discussed in http://article.gmane.org/gmane.linux.drivers.openib/61925
and follow-up messages, libraries using RDMA would like to track
precisely when application code changes memory mapping via free(),
munmap(), etc. Current pure-userspace solutions using malloc hooks

Hey Sean,
You define global int af_ib_support. It never gets set to non-zero.
Was this debug code or does it get set somewhere else that I'm missing?

It doesn't get set until a later patch in the series, once all the needed
infrastructure is in place.

I see that some IB nics can do multiqueu in ethernet mode.
Is there any work on multiqueue support for IPoIB going on?

No, although one could view connected mode as an even better place to
start, since you already get perfect classification by remote peer for
free.

I don't think this is really a merge-blocker, but this code seems to
have faith in the talismanic power of atomic_t to avoid races in nearby
code. The following anti-pattern appears in a few other variants in the
