Subject: SUNRPC: Silence WARN_ON when NFSv4.1 over RDMA is in use
From: Chuck Lever <chuck.lever@xxxxxxxxxx>
commit 16590a228109e2f318d2cc6466221134cfab723a upstream.
Using NFSv4.1 on RDMA should be safe, so broaden the new checks in
rpc_create().
WARN_ON_ONCE is used, matching most other WARN call sites in clnt.c.
Fixes: 39a9beab5acb ("rpc: share one xps between all backchannels")
Fixes: d50039ea5ee6 ("nfsd4/rpc: move backchannel create logic...")
