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.

At first look, mark_page_accessed() in follow_page() seems a bit strange. It seems pte_mkyoung() would be better consistent with other kernel code. However, it is intentional. The commit log said: ------------------------------------------------ commit 9e45f61d69be9024a2e6bef3831fb04d90fac7a8 Author: akpm <akpm> Date: Fri Aug 15 07:24:59 2003 +0000 [PATCH] Use mark_page_accessed() in follow_page() Touching a page via follow_page() counts as a reference so we should be either setting the referenced bit in the pte or running mark_page_accessed(). Altering the pte is tricky because we haven't implemented an atomic pte_mkyoung(). And mark_page_accessed() is better anyway because it has more aging state: it can move the page onto the active list. BKrev: 3f3c8acbplT8FbwBVGtth7QmnqWkIw ------------------------------------------------ The atomic issue is still true nowadays. adding comment help to understand code intention and it would be better.

shrink_inactive_list() scans in sc->swap_cluster_max chunks until it hits the scan limit it was passed. shrink_inactive_list() { do { isolate_pages(swap_cluster_max) shrink_page_list() } while (nr_scanned < max_scan); } This assumes that swap_cluster_max is not bigger than the scan limit because the latter is checked only after at least one iteration. In shrink_all_memory() sc->swap_cluster_max is initialized to the overall reclaim goal in the beginning but not decreased while reclaim is making progress which leads to subsequent calls to shrink_inactive_list() reclaiming way too much in the one iteration that is done unconditionally. Set sc->swap_cluster_max always to the proper goal before doing shrink_all_zones() shrink_list() shrink_inactive_list(). While the current shrink_all_memory() happily reclaims more than actually requested, this patch fixes it to never exceed the goal: unpatched wanted=10000 reclaimed=13356 wanted=10000 reclaimed=19711 wanted=10000 reclaimed=10289 wanted=10000 reclaimed=17306 wanted=10000 reclaimed=10700 wanted=10000 reclaimed=10004 wanted=10000 reclaimed=13301 wanted=10000 reclaimed=10976 wanted=10000 reclaimed=10605 wanted=10000 reclaimed=10088 wanted=10000 reclaimed=15000 patched wanted=10000 reclaimed=10000 wanted=10000 reclaimed=9599 wanted=10000 reclaimed=8476 wanted=10000 reclaimed=8326 wanted=10000 reclaimed=10000 wanted=10000 reclaimed=10000 wanted=10000 reclaimed=9919 wanted=10000 reclaimed=10000 wanted=10000 reclaimed=10000 wanted=10000 reclaimed=10000 wanted=10000 reclaimed=10000 wanted=10000 reclaimed=9624 wanted=10000 reclaimed=10000 wanted=10000 reclaimed=10000 wanted=8500 reclaimed=8092 wanted=316 reclaimed=316 Signed-off-by: Johannes Weiner <hannes@cmpxchg.org> Reviewed-by: MinChan Kim <minchan.kim@gmail.com> Acked-by: Nigel Cunningham <ncunningham@crca.org.au> Acked-by: "Rafael J.

Commit a79311c1 "vmscan: bail out of direct reclaim after swap_cluster_max pages" moved the nr_reclaimed counter into the scan control to accumulate the number of all reclaimed pages in a reclaim invocation. shrink_all_memory() can use the same mechanism. it increase code consistency and redability.

Therefore, swap-backed pages and file-backed pages have inconsistent behavior. mark_page_accessed() should be removed from do_swap_page().

Impact: cleanup In almost cases, for_each_zone() is used with populated_zone(). It's because almost function doesn't need memoryless node information. Therefore, for_each_populated_zone() can help to make code simplify. This patch has no functional change.

sc.may_swap does not only influence reclaiming of anon pages but pages mapped into pagetables in general, which also includes mapped file pages. In shrink_page_list(): if (!sc->may_swap && page_mapped(page)) goto keep_locked; For anon pages, this makes sense as they are always mapped and reclaiming them always requires swapping. But mapped file pages are skipped here as well and it has nothing to do with swapping. The real effect of the knob is whether mapped pages are unmapped and reclaimed or not. Rename it to `may_unmap' to have its name match its actual meaning more precisely.
