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).
