Maybe you can just add a case for IB_WR_SEND in this patch to avoid hurting bisectability. Looking at the uverbs part in patch 2, I think the changes are okay. I noticed there's a (__be32 __force) cast of the immediate data from userspace (it was already in the existing code). I wonder, why not define the field in the uapi struct as __be32 in the first place?
