[Question] Include isolated cpu to ensure that tasks are not scheduled to isolated cpu？

[zhengzucheng]

In a cpuset subsystem, cpuset.cpus contains isolated cpu and 
non-isolated cpu.
Is there any way to ensure that the task runs only on the non-isolated cpus?
eg：
isolcpus=1, cpusete.cpus=0-7. It is found that some tasks are scheduled 
to cpu1.

In addition, task run on isolated cpu cann't be scheduled to other cpu 
in the future.


Thanks!
