From 0245b3e787dc3267a915e1f56419e7e9c197e148 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 30 Oct 2005 15:00:01 -0800 Subject: [PATCH] [PATCH] swsusp: two simplifications The following patch simplifies the progress meter in disk.c:free_some_memory() and makes disk.c:pm_suspend_disk() call device_resume() explicitly in the suspend path.
