[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. Signed-off-by: Rafael J.
