From 442c9137de8d769053e81d325709dca72f0b5e44 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Fri, 23 Jun 2006 02:03:38 -0700 Subject: [PATCH] More page migration: do not inc/dec rss counters If we install a migration entry then the rss not really decreases since the page is just moved somewhere else. We can save ourselves the work of decrementing and later incrementing which will just eventually cause cacheline bouncing.
