Subject: [PATCH v4 2/8] SUNRPC: use rpcbind reference counting helpers
Date: Tue, 20 Sep 2011 14:13:49 +0400	[thread overview]
Message-ID: <20110920101349.9861.42381.stgit@localhost6.localdomain6> (raw)
In-Reply-To: <20110920101031.9861.18444.stgit@localhost6.localdomain6>

All is simple: we just increase users counter if rpcbind clients has been
created already. Otherwise we create them and set users counter to 1.
