I took these patches with the small edits I noted

   RDMA/rxe: Stop lookup of partially built objects
   RDMA/rxe: Convert read side locking to rcu
   RDMA/rxe: Cleanup rxe_pool.c

It seems OK, but we need to fix the AH problem at least in the destroy
path first - lets try to fix it in alloc as well?

I do not mean to bring more efforts to Bob.
But normally a new feature is merged into rdma. some test cases should also be added to rdma-core to verify this new feature.

But if Bob is busy with AH problem, I am OK with it.
