Don't bother checking for active pages in the swapout path. Not sure about this one. Clearly the page isn't *likely* to be on the active list, because the caller found it on the inactive list. But I don't see any locking which would prevent the page from getting bumped up to the active list in the meanwhile. Needs more explanation. ===================================== --- 2.4.19-pre3/mm/vmscan.c~aa-200-active_page_swapout Tue Mar 19 19:49:04 2002 +++ 2.4.19-pre3-akpm/mm/vmscan.c Tue Mar 19 19:49:04 2002 @@ -83,10 +83,6 @@ static inline int try_to_swap_out(struct return 0; } - /* Don't bother unmapping pages that are active */ - if (PageActive(page)) - return 0; - /* Don't bother replenishing zones not under pressure.. */ if (!memclass(page_zone(page), classzone)) return 0; - - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
