Subject: [PATCH v12 04/14] mm/vmalloc: rename vmap_*_range vmap_pages_*_range
Date: Tue, 2 Feb 2021 21:05:05 +1000 [thread overview]
Message-ID: <20210202110515.3575274-5-npiggin@gmail.com> (raw)
In-Reply-To: <20210202110515.3575274-1-npiggin@gmail.com>
The vmalloc mapper operates on a struct page * array rather than a
linear physical address, re-name it to make this distinction clear.
