Subject: [PATCH] btrfs: Remove stale comment about select_delayed_ref
Date: Thu, 17 May 2018 14:16:29 +0300	[thread overview]
Message-ID: <1526555789-14161-1-git-send-email-nborisov@suse.com> (raw)

select_delayed_ref really just gets the next delayed ref which has to
be processed - either an add ref or drop ref. We never go back for
anything. So the comment is actually bogus, just remove it.
