Subject: [PATCH v3 3/8] mm/vmalloc: rename vmap_*_range vmap_pages_*_range
Date: Mon, 10 Aug 2020 12:27:27 +1000 [thread overview]
Message-ID: <20200810022732.1150009-4-npiggin@gmail.com> (raw)
In-Reply-To: <20200810022732.1150009-1-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.
