PG_slab?

[Marcelo Tosatti <marcelo.tosatti@cyclades.com>]

Hi MM fellows,

What is PG_slab about?

#define PG_slab                  7      /* slab debug (Suparna wants this) */

Its not used by SLAB though:

[marcelo@xeon mm]$ grep -A5 -B5 PG_slab page_alloc.c
                        1 << PG_lru     |
                        1 << PG_private |
                        1 << PG_locked  |
                        1 << PG_active  |
                        1 << PG_reclaim |
                        1 << PG_slab    |
                        1 << PG_swapcache |
                        1 << PG_writeback )))
                bad_page(function, page);
        if (PageDirty(page))
                ClearPageDirty(page);
[marcelo@xeon mm]$

I suppose it was used by someone sometime ago but its not anymore?
