From 26f2c75cd2cf10a6120ef02ca9a94db77cc9c8e0 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Thu, 11 Aug 2016 14:58:24 +0200 Subject: sched/cputime: Fix omitted ticks passed in parameter Commit: f9bcf1e0e014 ("sched/cputime: Fix steal time accounting") ... fixes a leak on steal time accounting but forgets to account the ticks passed in parameters, assuming there is only one to take into account. Let's consider that parameter back.
