From 5c8806a037ad4f53259146060b32600566475e29 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 6 Jan 2012 15:10:44 -0800 Subject: rcu: Move RCU_TRACE to lib/Kconfig.debug The RCU_TRACE kernel parameter has always been intended for debugging, not for production use. Formalize this by moving RCU_TRACE from init/Kconfig to lib/Kconfig.debug. Signed-off-by: Paul E. McKenney Signed-off-by: Paul E.
