From 16590a228109e2f318d2cc6466221134cfab723a Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 22 Aug 2016 14:57:42 -0400 Subject: SUNRPC: Silence WARN_ON when NFSv4.1 over RDMA is in use 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...") Signed-off-by: Chuck Lever Reviewed-by: J.
