From 558d0f86d12020c3c8512c8d901391720f66c839 Mon Sep 17 00:00:00 2001

Subject: [PATCH 190/274] rt/rcutree: Move misplaced prototype
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Fix this warning on x86 defconfig:
kernel/rcutree.h:433:13: warning: ‘rcu_preempt_qs’ declared ‘static’ but never defined [-Wunused-function]
The #ifdefs and prototypes here are a maze, move it closer to the
usage site that needs it.
