Subject: [PATCH-cgroup 0/2] cgroup/cpuset: Account for boot time isolated CPUs

The current cpuset code and test_cpuset_prs.sh test have not fully
account for the possibility of pre-isolated CPUs added by the "isolcpus"
boot command line parameter. This patch series modifies them to do the
right thing whether or not "isolcpus" is present or not.

The updated test_cpuset_prs.sh was run successfully with or without the
"isolcpus" option.

Waiman Long (2):
  cgroup/cpuset: Account for boot time isolated CPUs
  selftest/cgroup: Make test_cpuset_prs.sh deal with pre-isolated CPUs
