Subject[PATCH v4 2/4] sched/isolation: Extend nohz_full to isolate managed IRQs
Date
Extend nohz_full feature set to include isolation from managed IRQS. This
is required specifically for setups that only uses nohz_full and still
requires isolation for maintaining lower latency for the listed CPUs.
