From: Miles Chen <miles.chen@mediatek.com>
The commit d6e0b7fa1186 ("slub: make dead caches discard free slabs immediately") makes put_cpu_partial() run with preemption disabled and interrupts disabled when calling unfreeze_partials().
The comment: "put_cpu_partial() is done without interrupts disabled and without preemption disabled" looks obsolete, so remove it.
