[PATCH] mm: zap_pte_range dec rss
Small adjustment: zap_pte_range decrement its rss counts from 0 then finally add, avoiding negations - we don't have or need a sub_mm_rss. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
