Actually, sorry, but this file calls kzalloc_node() which comes from
linux/slab.h, no? Can we keep the include then? slab.h is probably
included by other include files but for clarity it's better that
hugetlb_cgroup.c to include slab.h if it is calling functions declared
there.

I have browsed the code to verify it but I still missed kzalloc_node in this file.
Will drop this patch. Many thanks for your review.
