Wysocki" , Ingo Molnar , Steven Rostedt , Vincent Guittot From: Christian Loehle Subject: [PATCH] idle: Remove stale RCU comment Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset="utf-8" The call of rcu_idle_enter() from within cpuidle_idle_call() was removed in commit 1098582a0f6c ("sched,idle,rcu: Push rcu_idle deeper into the idle path") which makes the comment out of place.
