The patch titled vmscan: respect higher order in zone_reclaim() has been removed from the -mm tree. Its filename was vmscan-respect-higher-order-in-zone_reclaim.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: vmscan: respect higher order in zone_reclaim() From: Johannes Weiner <hannes@xxxxxxxxxxx> During page allocation, there are two stages of direct reclaim that are applied to each zone in the preferred list. The first stage using zone_reclaim() reclaims unmapped file backed pages and slab pages if over defined limits as these are cheaper to reclaim. The caller specifies the order of the target allocation but the scan control is not being correctly initialised. The impact is that the correct number of pages are being reclaimed but that lumpy reclaim is not being applied. This increases the chances of a full direct reclaim via try_to_free_pages() is required. This patch initialises the order field of the scan control as requested by the caller.
