From 764d5fcc2a58d789629f6800451975fc93f25822 Mon Sep 17 00:00:00 2001 From: Christian Loehle Date: Mon, 3 Jun 2024 16:30:39 +0100 Subject: [PATCH] idle: Remove stale RCU comment 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.
