+RDMA

Jakub, David

Can we please ask that everything directly or indirectly related to RDMA
will be sent to linux-rdma@ too?

Maybe it is only description that needs to be updated, but I would
expect to see call to pcie_relaxed_ordering_enabled() before setting
relaxed_ordering to always true.

If we are talking about RDMA, the IB_ACCESS_RELAXED_ORDERING flag should
be taken into account too.

Thanks
