From: Nishanth Aravamudan Date: Wed, 26 Mar 2008 21:37:53 +0000 (-0700) Subject: hugetlb: indicate surplus huge page counts in per-node meminfo X-Git-Tag: v2.6.25-rc8~81 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a1de09195b294c6a4c5dec8c8defd0a2688d3f75;p=linux-2.6 hugetlb: indicate surplus huge page counts in per-node meminfo Currently we show the surplus hugetlb pool state in /proc/meminfo, but not in the per-node meminfo files, even though we track the information on a per-node basis. Printing it there can help track down dynamic pool bugs including the one in the follow-on patch.
