[PATCH v3, part4 09/39] mm: use totalram_pages instead of num_physpages at runtime
From: Jiang Liu <hidden>
Date: 2013-03-26 15:58:35
Also in:
linux-arch, linux-mm, lkml
Subsystem:
filesystems (vfs and infrastructure), fuse filesystem [core], hibernation (aka software suspend, aka swsusp), networking [general], networking [ipv4/ipv6], suspend to ram, the rest · Maintainers:
Alexander Viro, Christian Brauner, Miklos Szeredi, "Rafael J. Wysocki", "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, David Ahern, Ido Schimmel, Linus Torvalds
The global variable num_physpages is scheduled to be removed, so use totalram_pages instead of num_physpages at runtime. Signed-off-by: Jiang Liu <redacted> Cc: Miklos Szeredi <miklos@szeredi.hu> Cc: "David S. Miller" <davem@davemloft.net> Cc: Alexey Kuznetsov <redacted> Cc: James Morris <jmorris@namei.org> Cc: Hideaki YOSHIFUJI <redacted> Cc: Patrick McHardy <redacted> Cc: fuse-devel@lists.sourceforge.net Cc: linux-kernel@vger.kernel.org Cc: netdev@vger.kernel.org --- Hi all, Sorry for my mistake that my previous patch series has been screwed up. So I regenerate a third version and also set up a git tree at: git://github.com/jiangliu/linux.git mem_init Any help to review and test are welcomed! Regards!
