[PATCH-next v2 0/2] cgroup/cpuset: Run SCHED_DEADLINE shrink test on valid partition root only

[Waiman Long <longman@redhat.com>]

v2:
 - Leave the v1 code as is and switch between using is_cpu_exclusive()
   for v1 and is_partition_valid() for v2.

When testing some upstream cpuset patch, it was found that the current
SCHED_DEADLINE shrink test in validate_change() can incorrectly get
triggered due to the fact that the exclusive flag may get set on a
cpuset that is not a valid partition root. This series fixes this
problem by making sure that the test will only be triggered on a valid
partition root and remove the now unnecessary code to handle the
exclusive flag in the v2 code.

Waiman Long (2):
  cgroup/cpuset: Run SCHED_DEADLINE shrink test on valid partition root
    only
  cgroup/cpuset: Remove CS_CPU_EXCLUSIVE handling code from v2
