Date: Tue, 25 Oct 2011 14:17:08 +0300 From: Stanislav Kinsbursky <skinsbursky@...allels.com> To: Trond.Myklebust@...app.com Cc: linux-nfs@...r.kernel.org, xemul@...allels.com, neilb@...e.de, netdev@...r.kernel.org, linux-kernel@...r.kernel.org, bfields@...ldses.org, davem@...emloft.net, devel@...nvz.org Subject: [PATCH v6 4/8] 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.
