Perhaps we could add a little more information here. It was added in 2014 by 5dfb41750992 ("sl[au]b: charge slabs to kmemcg explicitly"). The need for it was removed in 2020 by 1f3147b49d75 ("mm: slub: call account_slab_page() after slab page initialization"). Reviewed-by: Matthew Wilcox (Oracle) <willy@xxxxxxxxxxxxx>
