SUNRPC: rpcb_register() should handle errors silently
Move error reporting for RPC registration to rpcb_register's caller. This way the caller can choose to recover silently from certain errors, but report errors it does not recognize. Error reporting for kernel RPC service registration is now handled in one place. This patch is part of a series that addresses http://bugzilla.kernel.org/show_bug.cgi?id=12256 Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
