From 6bfbaa51ed47774492d83d182a86068cc35aa4c6 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Fri, 3 Feb 2017 21:37:49 +0100 Subject: sched/headers, RCU: Move rcu_copy_process() from to kernel/fork.c Move rcu_copy_process() into kernel/fork.c, which is the only user of this inline function. This simplifies to the level that does not have to be included in it anymore - which change is done in a subsequent patch.
