From 25761b6eb7b33823bcfff6bfe2a015badcd76fb8 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 30 Oct 2005 14:59:56 -0800 Subject: [PATCH] swsusp: move snapshot functionality to separate file The following patch moves the functionality of swsusp related to creating and handling the snapshot of memory to a separate file, snapshot.c This should enable us to untangle the code in the future and eventually to implement some parts of swsusp.c in the user space. The patch does not change the code. Signed-off-by: Rafael J.
