From 54d6d3039e2d84b6fbfbe59ec57d856371edf0a2 Mon Sep 17 00:00:00 2001 From: Daniel Bristot de Oliveira Date: Mon, 29 May 2017 16:24:02 +0200 Subject: [PATCH] sched/deadline: Fix dl_bw comment The sched_dl_entity's dl_bw variable stores the utilization (dl_runtime / dl_period) of a task, not its density (dl_runtime / dl_deadline), as the comment says.
