From 50f7ccc64750610f57983720613713b2c14f0e9c Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 16 Aug 2018 12:55:01 +0200 Subject: [PATCH] cpuidle: menu: Update stale polling override comment The comment to explain why the menu governor uses idle state 1 instead of idle state 0 as the first one sometimes is stale (among other things it mentions a user setting not present any more), so update it.
