Subject: [PATCH] mm/mm_init.c: don't initialize page->lru again
Date: Wed, 5 Jun 2024 22:14:36 +0000 [thread overview]
Message-ID: <20240605221436.24627-1-richard.weiyang@gmail.com> (raw)
After init_reserved_page(), we expect __init_single_page() has done its
work to the page, which already initialize page->lru properly.
We don't need to do it again.
