By moving page->private to the fourth word of struct page, we can put the SLUB counters in the same word as SLAB's s_mem and still do the cmpxchg_double trick. Now the SLUB counters no longer overlap with the mapcount or refcount so we can drop the call to page_mapcount_reset() and simplify set_page_slub_counters() to a single line.
