Date: Wed, 19 Jun 2019 17:29:55 -0400 (EDT) From: David Miller <davem@...emloft.net> To: mka@...omium.org Cc: kuznet@....inr.ac.ru, yoshfuji@...ux-ipv6.org, alexander.h.duyck@...hat.com, netdev@...r.kernel.org, linux-kernel@...r.kernel.org, dianders@...omium.org Subject: Re: [PATCH] net/ipv4: fib_trie: Avoid cryptic ternary expressions From: Matthias Kaehlcke <mka@...omium.org> Date: Tue, 18 Jun 2019 14:14:40 -0700 > empty_child_inc/dec() use the ternary operator for conditional > operations. The conditions involve the post/pre in/decrement > operator and the operation is only performed when the condition > is *not* true. This is hard to parse for humans, use a regular > 'if' construct instead and perform the in/decrement separately. > > This also fixes two warnings that are emitted about the value > of the ternary expression being unused, when building the kernel > with clang + "kbuild: Remove unnecessary -Wno-unused-value" > (https://lore.kernel.org/patchwork/patch/1089869/): > > CC net/ipv4/fib_trie.o > net/ipv4/fib_trie.c:351:2: error: expression result unused [-Werror,-Wunused-value] > ++tn_info(n)->empty_children ? : ++tn_info(n)->full_children; > > Signed-off-by: Matthias Kaehlcke <mka@...omium.org> Applied to net-next, thanks.
