Subject: [PATCH v2 2/5] SUNRPC: use rpcbind reference counting helpers
Date: Fri, 09 Sep 2011 16:08:36 +0400	[thread overview]
Message-ID: <20110909120836.13697.24968.stgit@localhost6.localdomain6> (raw)
In-Reply-To: <20110909115146.13697.71682.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.
