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

From: Frederic Weisbecker
Date: Wed May 27 2020 - 10:29:18 EST

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.


HEAD: 774258ad06e832e9fbdcf681225d2c29421a100f


Marcelo Tosatti (2):
kthread: Switch to cpu_possible_mask
isolcpus: Affine unbound kernel threads to housekeeping cpus
