Rik van Riel 52bf84aa20 sched/numa, mm: Remove p->numa_migrate_deferred ... Excessive migration of pages can hurt the performance of workloads that span multiple NUMA nodes. However, it turns out that the p->numa_migrate_deferred knob is a really big hammer, which does reduce migration rates, but does not actually help performance. Now that the second stage of the automatic numa balancing code has stabilized, it is time to replace the simplistic migration deferral code with something smarter.
