From 91ec6778ec4f963fcb2c2793610919b572f633b0 Mon Sep 17 00:00:00 2001 From: Juri Lelli Date: Fri, 19 Sep 2014 10:22:41 +0100 Subject: [PATCH] sched/deadline: Fix inter- exclusive cpusets migrations Users can perform clustered scheduling using the cpuset facility. After an exclusive cpuset is created, task migrations happen only between CPUs belonging to the same cpuset. Inter- cpuset migrations can only happen when the user requires so, moving a task between different cpusets. This behaviour is broken in SCHED_DEADLINE, as currently spurious inter- cpuset migration may happen without user intervention. This patch fix the problem (and shuffles the code a bit to improve clarity).
