nvme-rdma: wait for local invalidation before completing a request

Browse source

We must not complete a request before the host memory region is
invalidated.  Luckily we have send with invalidate protocol support so
we usually don't need to execute it, but in case the target did not
invalidate a memory region for us, we must wait for the invalidation to
complete before unmapping host memory and completing the I/O.
