From fcd99434fb5c137274d2e15dd2a6a7455f0f29ff Mon Sep 17 00:00:00 2001 From: Veaceslav Falico Date: Tue, 2 Apr 2013 05:15:16 +0000 Subject: bonding: get netdev_rx_handler_unregister out of locks Now that netdev_rx_handler_unregister contains synchronize_net(), we need to call it outside of bond->lock, cause it might sleep. Also, remove the already unneded synchronize_net(). Signed-off-by: Veaceslav Falico Acked-by: Eric Dumazet Signed-off-by: David S.
