workqueue.debug_force_rr_cpu
Workqueue used to implicitly guarantee that work
items queued without explicit CPU specified are put
on the local CPU. This guarantee is no longer true
and while local CPU is still preferred work items
may be put on foreign CPUs. This debug option
forces round-robin CPU selection to flush out
usages which depend on the now broken guarantee.
When enabled, memory and cache locality will be
impacted.
