From ae91aa0adb14dc33114d566feca2f7cb7a96b8b7 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 15 May 2017 15:30:32 -0700 Subject: rcu: Remove debugfs tracing RCU's debugfs tracing used to be the only reasonable low-level debug information available, but ftrace and event tracing has since surpassed the RCU debugfs level of usefulness. This commit therefore removes RCU's debugfs tracing. Signed-off-by: Paul E.
