The patch titled Subject: mm: vmscan: count only dirty pages as congested has been removed from the -mm tree. Its filename was mm-vmscan-count-only-dirty-pages-as-congested.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Jamie Liu <jamieliu@xxxxxxxxxx> Subject: mm: vmscan: count only dirty pages as congested shrink_page_list() counts all pages with a mapping, including clean pages, toward nr_congested if they're on a write-congested BDI. shrink_inactive_list() then sets ZONE_CONGESTED if nr_dirty == nr_congested. Fix this apples-to-oranges comparison by only counting pages for nr_congested if they count for nr_dirty.
