Subject: [PATCH v5 3/8] mm/vmalloc: rename vmap_*_range vmap_pages_*_range
Date: Fri, 21 Aug 2020 14:44:22 +1000 [thread overview]
Message-ID: <20200821044427.736424-4-npiggin@gmail.com> (raw)
In-Reply-To: <20200821044427.736424-1-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.
