mm: slab/slub: use page->list consistently instead of page->lru
'struct page' has two list_head fields: 'lru' and 'list'. Conveniently,
they are unioned together. This means that code can use them
interchangably, which gets horribly confusing like with this nugget from
slab.c:
> list_del(&page->lru);
> if (page->active == cachep->num)
> list_add(&page->list, &n->slabs_full);
This patch makes the slab and slub code use page->lru universally instead
of mixing ->list and ->lru.
So, the new rule is: page->lru is what the you use if you want to keep
your page on a list. Don't like the fact that it's not called ->list?
Too bad.
