From ca0aec0f7a94bf9f07fefa8bfd23282d4e8ceb8a Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 6 Jan 2006 00:15:56 -0800 Subject: [PATCH] swsusp: make image size limit tunable Make the suspend image size limit tunable via /sys/power/image_size. It is necessary for systems on which there is a limited amount of swap available for suspend. It can also be useful for optimizing performance of swsusp on systems with 1 GB of RAM or more.
