Patches 2 and 3 fixes the CLONE_INTO_CGROUP > problem in cpuset. Patch 4 is a minor fix. The last patch is a > performance optimization patch for the non-CLONE_INTO_CGROUP case. Applied 1-4 to cgroup/for-6.3-fixes w/ stable cc'd. Given that the fixes are a bit involved, the breakages have been there for quite a while and the cpuset code has changed quite a bit, backporting might not be trivial tho. Let's see how that goes.
