From: MengEn Sun <mengensun@xxxxxxxxxxx> when we do not config percpu_pagelist_high_fraction the kernel compute the pcp high_min/max by itself, which may be not easy to tell the really high_min/max. we output the pcp high_min/max to the zoneinfo Reviewed-by: Jinliang Zheng <alexjlzheng@xxxxxxxxxxx> Signed-off-by: MengEn Sun <mengensun@xxxxxxxxxxx> --- mm/vmstat.c | 12 ++++++++---- 1 file changed, 8 insertions(+), 4 deletions(-) diff --git a/mm/vmstat.c b/mm/vmstat.c index b5a4cea423e1..1917c034c045 100644 --- a/mm/vmstat.c +++ b/mm/vmstat.c @@ -1791,13 +1791,17 @@ static void zoneinfo_show_print(struct seq_file *m, pg_data_t *pgdat, pcp = per_cpu_ptr(zone->per_cpu_pageset, i); seq_printf(m, "\n cpu: %i" - "\n count: %i" - "\n high: %i" - "\n batch: %i", + "\n count: %i" + "\n high: %i" + "\n batch: %i" + "\n high_min: %i" + "\n high_max: %i", i, pcp->count, pcp->high, - pcp->batch); + pcp->batch, + pcp->high_min, + pcp->high_max); #ifdef CONFIG_SMP pzstats = per_cpu_ptr(zone->per_cpu_zonestats, i); seq_printf(m, "\n vm stats threshold: %d", -- 2.43.5
