From c24f72cc7ca829bbad0532ddf315ace3ae1c359e Mon Sep 17 00:00:00 2001 From: Joel Becker Date: Sat, 3 Feb 2007 03:14:30 -0800 Subject: ocfs2: Proper cleanup in case of error in ocfs2_register_hb_callbacks() If ocfs2_register_hb_callbacks() succeeds on its first callback but fails its second, it doesn't release the first on the way out. Fix that. While we're at it, o2hb_unregister_callback() never returns anything but 0, so let's make it void.
