The patch titled Subject: mm/vmscan: push lruvec pointer into get_scan_count() has been removed from the -mm tree. Its filename was mm-vmscan-push-lruvec-pointer-into-get_scan_count.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/ ------------------------------------------------------ From: Konstantin Khlebnikov <khlebnikov@xxxxxxxxxx> Subject: mm/vmscan: push lruvec pointer into get_scan_count() Signed-off-by: Konstantin Khlebnikov <khlebnikov@xxxxxxxxxx> Cc: Mel Gorman <mel@xxxxxxxxx> Cc: KAMEZAWA Hiroyuki <kamezawa.hiroyu@xxxxxxxxxxxxxx> Acked-by: Hugh Dickins <hughd@xxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- mm/vmscan.c | 25 +++++++++---------------- 1 file changed, 9 insertions(+), 16 deletions(-) diff -puN mm/vmscan.c~mm-vmscan-push-lruvec-pointer-into-get_scan_count mm/vmscan.c --- a/mm/vmscan.c~mm-vmscan-push-lruvec-pointer-into-get_scan_count +++ a/mm/vmscan.c @@ -150,11 +150,6 @@ static bool global_reclaim(struct scan_c } #endif -static struct zone_reclaim_stat *get_reclaim_stat(struct mem_cgroup_zone *mz) -{ - return &mem_cgroup_zone_lruvec(mz->zone, mz->mem_cgroup)->reclaim_stat; -} - static unsigned long get_lruvec_size(struct lruvec *lruvec, enum lru_list lru) { if (!mem_cgroup_disabled()) @@ -1581,20 +1576,18 @@ static int vmscan_swappiness(struct scan * * nr[0] = anon pages to scan; nr[1] = file pages to scan */ -static void get_scan_count(struct mem_cgroup_zone *mz, struct scan_control *sc, +static void get_scan_count(struct lruvec *lruvec, struct scan_control *sc, unsigned long *nr) { unsigned long anon, file, free; unsigned long anon_prio, file_prio; unsigned long ap, fp; - struct zone_reclaim_stat *reclaim_stat = get_reclaim_stat(mz); + struct zone_reclaim_stat *reclaim_stat = &lruvec->reclaim_stat; u64 fraction[2], denominator; enum lru_list lru; int noswap = 0; bool force_scan = false; - struct lruvec *lruvec; - - lruvec = mem_cgroup_zone_lruvec(mz->zone, mz->mem_cgroup); + struct zone *zone = lruvec_zone(lruvec); /* * If the zone or memcg is small, nr[l] can be 0.
