Subject[PATCH] swsusp: Fix memory shrinker
Date
Hi,

I think this is 2.6.21 material.

---
From: Rafael J. Wysocki <rjw@sisk.pl>

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. Wysocki <rjw@sisk.pl>
