Please pull RDMA subsystem changes

Hi Linus,

I don't usually send rc PRs so late but this cycle there are some urgent user triggerable bugs that should be expedited. As per your request I've been putting most of the discovered bugs into the merge window stream, these ones stood out as particularly significant.

Thanks,
Jason
