From c07e02db76940c75fc92f2f2c9adcdbb09ed70d0 Mon Sep 17 00:00:00 2001 From: Martin Hicks Date: Sat, 3 Sep 2005 15:55:11 -0700 Subject: [PATCH] VM: add page_state info to per-node meminfo Add page_state info to the per-node meminfo file in sysfs. This is mostly just for informational purposes. The lack of this information was brought up recently during a discussion regarding pagecache clearing, and I put this patch together to test out one of the suggestions. It seems like interesting info to have, so I'm submitting the patch.
