Subject: [PATCH 05/22] linux/printk.h: use DYNAMIC_DEBUG_BRANCH in pr_debug_ratelimited
Date:   Thu, 20 Sep 2018 00:04:27 +0200
Message-Id: <20180919220444.23190-6-linux@rasmusvillemoes.dk>
In-Reply-To: <20180919220444.23190-1-linux@rasmusvillemoes.dk>
References: <20180919220444.23190-1-linux@rasmusvillemoes.dk>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

pr_debug_ratelimited tests the dynamic debug descriptor the old-fashioned
way, and doesn't utilize the static key/jump label implementation on
architectures that HAVE_JUMP_LABEL. Use the DYNAMIC_DEBUG_BRANCH which
is defined appropriately.
