Wysocki" Date: Wed, 4 Apr 2007 19:08:21 -0700 Subject: [PATCH] swsusp: fix memory shrinker Fix a bug in the swsusp's memory shrinker that causes some systems using highmem to refuse to suspend to disk if image_size is set above 1/2 of available RAM. Special thanks to Jiri Slaby for reporting the problem and assistance in debugging it. Signed-off-by: Rafael J.
