The quilt patch titled Subject: vmstat: call fold_vm_zone_numa_events() before show per zone NUMA event has been removed from the -mm tree. Its filename was vmstat-call-fold_vm_zone_numa_events-before-show-per-zone-numa-event.patch
This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
------------------------------------------------------ From: MengEn Sun mengensun@tencent.com Subject: vmstat: call fold_vm_zone_numa_events() before show per zone NUMA event Date: Fri, 1 Nov 2024 12:06:38 +0800
Since 5.14-rc1, NUMA events will only be folded from per-CPU statistics to per zone and global statistics when the user actually needs it.
Currently, the kernel has performs the fold operation when reading /proc/vmstat, but does not perform the fold operation in /proc/zoneinfo. This can lead to inaccuracies in the following statistics in zoneinfo: - numa_hit - numa_miss - numa_foreign - numa_interleave - numa_local - numa_other
Therefore, before printing per-zone vm_numa_event when reading /proc/zoneinfo, we should also perform the fold operation.
