It's NR_SLAB_RECLAIMABLE in __vm_enough_memory. And that is always
zero with SLOB. There aren't any reclaimable slab pages.
SLOB does do UNRECLAIMABLE, true. But there aren't any interesting
users of SLAB_UNRECLAIMABLE that I can see.

That's because there are no slabs! Memory usage shows up here in
exactly the same way that memory usage from get_free_page does.
