From a0a4a85a15df6335e3d11f83b2ac06ebebea313f Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 13 Oct 2010 04:43:04 +0000 Subject: [PATCH] fib: remove a useless synchronize_rcu() call fib_nl_delrule() calls synchronize_rcu() for no apparent reason, while rtnl is held. I suspect it was done to avoid an atomic_inc_not_zero() in fib_rules_lookup(), which commit 7fa7cb7109d07 added anyway. Signed-off-by: Eric Dumazet Signed-off-by: David S.
