After "mm, vmstat: print non-populated zones in zoneinfo", /proc/zoneinfo will show unpopulated zones. A memoryless node, having no populated zones at all, was previously ignored, but will now trigger the WARN() in is_zone_first_populated(). Remove this warning, as its only purpose was to warn of a situation that has since been enabled. Signed-off-by: Reza Arbab <arbab@xxxxxxxxxxxxxxxxxx> --- Aside: The "per-node stats" are still printed under the first populated zone, but that's not necessarily the first stanza any more. I'm not sure which criteria is more important with regard to not breaking parsers, but it looks a little weird to the eye. mm/vmstat.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/mm/vmstat.c b/mm/vmstat.c index f5fa1bd..76f7367 100644 --- a/mm/vmstat.c +++ b/mm/vmstat.c @@ -1359,8 +1359,6 @@ static bool is_zone_first_populated(pg_data_t *pgdat, struct zone *zone) return zone == compare; } - /* The zone must be somewhere! */ - WARN_ON_ONCE(1); return false; } -- 1.8.3.1 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
