Subject: [PATCH] mm/slub.c: replace cpu_slab->partial with wrapped APIs
Date: Mon, 17 Feb 2020 23:04:55 +0800 [thread overview]
Message-ID: <1581951895-3038-1-git-send-email-qiwuchen55@gmail.com> (raw)
From: chenqiwu <chenqiwu@xiaomi.com>
There are slub_percpu_partial() and slub_set_percpu_partial()
APIs to wrap kmem_cache->cpu_partial. This patch will use the
two to replace cpu_slab->partial in slub code.
