SUNRPC: setup rpcbind clients if service requires it
New function ("svc_uses_rpcbind") will be used to detect, that new service will send portmapper register calls. For such services we will create rpcbind clients and remove all stale portmap registrations. Also, svc_rpcb_cleanup() will be set as sv_shutdown callback for such services in case of this field wasn't initialized earlier. This will allow to destroy rpcbind clients when no other users of them left. Note: Currently, any creating service will be detected as portmap user. Probably, this is wrong. But now it depends on program versions "vs_hidden" flag. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
