staging/lustre: fix build in linux-next/akpm tree

Hi Andrew,

Bellow five patches convert Lustre client to new shrinker API and also adapt num_physpages removal linux-next/akpm tree. Since both changes are not in Greg's staging tree, I'm sending them to you so that Lustre can build properly in linux-next.

Thanks,
Tao
