Subject: [PATCH 1/1] mm: implement ->map_pages for shmem/tmpfs
Date: Fri, 28 Feb 2014 14:18:51 -0800 [thread overview]
Message-ID: <1393625931-2858-2-git-send-email-quning@google.com> (raw)
In-Reply-To: <1393625931-2858-1-git-send-email-quning@google.com>
In shmem/tmpfs, we also use the generic filemap_map_pages,
seems the additional checking is not worth a separate version
of map_pages for it.
