From 43a0a2a7d725f2ed2547cd656749eb66c093f2c2 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 17 May 2017 09:19:44 -0700 Subject: rcu: Move RCU debug Kconfig options to kernel/rcu RCU's debugging Kconfig options are in the unintuitive location lib/Kconfig.debug, and there are enough of them that it would be good for them to be more centralized. This commit therefore extracts RCU's Kconfig options from init/Kconfig into a new kernel/rcu/Kconfig.debug file. Reported-by: Ingo Molnar Signed-off-by: Paul E.
