Subject: [PATCH] mm: remove obsolete comment above struct per_cpu_pages
Date: Thu, 6 Jul 2023 17:24:41 +0800 [thread overview]
Message-ID: <20230706092441.1574950-1-linmiaohe@huawei.com> (raw)
Since commit 01b44456a7aa ("mm/page_alloc: replace local_lock with
normal spinlock"), per_cpu_pages is protected by normal spinlock.
Remove the obsolete comment as it's not that helpful.
