Subject: [PATCH v2 02/33] mm/slab: Dissolve slab_map_pages() in its caller
Date: Wed, 1 Dec 2021 19:14:39 +0100 [thread overview]
Message-ID: <20211201181510.18784-3-vbabka@suse.cz> (raw)
In-Reply-To: <20211201181510.18784-1-vbabka@suse.cz>
The function no longer does what its name and comment suggests, and just sets
two struct page fields, which can be done directly in its sole caller.
