From 32c141a0a1dfa29e0a07d78bec0c0919fc4b9f88 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 30 Mar 2010 10:59:28 -0700 Subject: rcu: fix now-bogus rcu_scheduler_active comments. The rcu_scheduler_active check has been wrapped into the new debug_lockdep_rcu_enabled() function, so update the comments to reflect this new reality. Signed-off-by: Paul E.
