Subject: [PATCH 2/8] mm/bootmem_info: drop initialization of page->lru
Date: Mon, 11 May 2026 16:05:30 +0200	[thread overview]
Message-ID: <20260511-bootmem_info_prep-v1-2-3fb0be6fc688@kernel.org> (raw)
In-Reply-To: <20260511-bootmem_info_prep-v1-0-3fb0be6fc688@kernel.org>

In the past, we used to store the type in page->lru.next, introduced by
commit 5f24ce5fd34c ("thp: remove PG_buddy"). The location changed over
the years; ever since commit 0386aaa6e9c8 ("bootmem: stop using
page->index"), we store it alongside the info in page->private.

Consequently, there is no need to reset page->lru anymore.
