From 9b65ef59d42a56fa1358958ede77aaa5bac385a8 Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Wed, 22 Mar 2006 00:09:09 -0800 Subject: [PATCH] [PATCH] fix swap cluster offset When we've allocated SWAPFILE_CLUSTER pages, ->cluster_next should be the first index of swap cluster. But current code probably sets it wrong offset.
