For reference: https://lore.kernel.org/lkml/20230125073502.743446-1-leobras@redhat.com/
And the latest proposal: https://lore.kernel.org/lkml/Y90mZQhW89HtYfT9@dhcp22.suse.cz/

Pcp cache draining isolation needs a function that abstracts checking
if a CPU is isolated through isolcpus= or nohz_full=. Take advantage
of that to do some cleanups.

Frederic Weisbecker (2):
  sched/isolation: Merge individual nohz_full features into a common
    housekeeping flag
  sched/isolation: Add cpu_is_isolated() API
