From 2a64255019e13dd975f1487cec32b873bcb76da6 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 19 May 2011 18:41:03 -0400 Subject: [PATCH] rxrpc: Fix set but unused variable 'usage' in rxrpc_get_peer(). I backed off from trying to just eliminate this variable, since transforming atomic_inc_return() into atomic_inc() takes away the memory barriers. Signed-off-by: David S.
