Subject: [PATCH 0/2] sched/isolation: Isolate unbound kthreads

Kthreads are harder to affine and isolate than user tasks. They can't
be placed inside cgroups/cpusets and the affinity for any newly
created kthread is always overriden from the inherited kthreadd's
affinity to system wide. Take that into account for nohz_full.

Thanks,
