From c60099bfe3a5e6fa22a930627689b3769c52153f Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Tue, 17 Oct 2006 00:09:59 -0700 Subject: [PATCH] swsusp: fix memory leaks My fancy new swsusp IO code had a big memory leak. It's somewhat invisible because the whole mem_map[] gets overwritten after resume, but it can cause us to get low on memory during the actual suspend process. Cc: "Rafael J.
