Subject: [PATCH] PM / Hibernate: Restore old swap signature to avoid user space breakage
Date: Sun, 5 Dec 2010 23:24:30 +0100	[thread overview]
Message-ID: <201012052324.30231.rjw@sisk.pl> (raw)

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

Commit 3624eb0 (PM / Hibernate: Modify signature used to mark swap)
modified hibernate signature used to mark swap partitions containing
hibernation images, but that turns out to have caused problems in
libblkid on recent Ubuntu.  Restore the old signature to avoid those
problems.
