Subject: Strange VM stats in /proc/zoneinfo
Date: Wed, 15 Aug 2012 11:05:27 +0200 [thread overview]
Message-ID: <201208151105.27411.ptesarik@suse.cz> (raw)
Hi folks,
while looking at my /proc/zoneinfo, I noticed that the counters are a bit
strange:
Node 0, zone DMA
pages free 3945
min 7
low 8
high 10
scanned 0
spanned 4080
present 3905
nr_free_pages 3945
OK, you'll probably argue that the rest is hidden in PCP differentials... BUT:
1. this machine has only 2 CPUs
2. stat_threshold = 4
3. vm_stat_diff[NR_FREE_PAGES] = 0 on both CPUs
Is this only me? Or do I misrepresent what these number actually tell?
TIA,
Petr Tesarik
