From 6313c1e0992feaee56bc09b85042b3186041fa3c Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Mon, 16 Apr 2007 17:00:53 -0700 Subject: [RTNETLINK]: Remove unnecessary locking in dump callbacks Since we're now holding the rtnl during the entire dump operation, we can remove additional locking for rtnl protected data. This patch does that for all simple cases (dev_base_lock for dev_base walking, RCU protection for FIB rule dumping). Signed-off-by: Patrick McHardy Signed-off-by: David S.
