From 0c03eca3d995e73d691edea8c787e25929ec156d Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 7 Aug 2012 00:47:11 +0000 Subject: net: fib: fix incorrect call_rcu_bh() After IP route cache removal, I believe rcu_bh() has very little use and we should remove this RCU variant, since it adds some cycles in fast path. Anyway, the call_rcu_bh() use in fib_true is obviously wrong, since some users only assert rcu_read_lock(). Signed-off-by: Eric Dumazet Cc: "Paul E. McKenney" Signed-off-by: David S.
