Wysocki <rjw@...k.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. Signed-off-by: Rafael J.
