From f2d613799af915da1fd78463ba8ec5086a0d6f92 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 27 Sep 2005 21:45:32 -0700 Subject: [PATCH] [PATCH] swsusp: prevent possible memory leak Prevent swsusp from leaking some memory in case of an error in read_pagedir(). It also prevents the BUG_ON() from triggering if there's an error while reading swap. Signed-off-by: Rafael J.
