R. Silva" To: "David S. Miller" Return-path: Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that in this particular case I replaced the "NOBREAK" comment with a "fall through" comment, which is what GCC is expecting to find. Signed-off-by: Gustavo A. R.
