Subject: [PATCH RESEND] PM/Hibernate: use rb_entry
Date: Mon, 01 Oct 2012 12:12:52 +0200 [thread overview]
Message-ID: <1349086372.2721.1.camel@offbook> (raw)
Since the software suspend extents are organized in an rbtree, use rb_entry
instead of container_of, as it is semantically more appropriate in order to
get a node as it is iterated.
