Subject: [PATCH 03/20] refs_ref_iterator_begin(): new function
Date: Mon, 20 Mar 2017 17:33:08 +0100	[thread overview]
Message-ID: <840b199ad58f11a690c684ad110807ed81d3b0eb.1490026594.git.mhagger@alum.mit.edu> (raw)
In-Reply-To: <cover.1490026594.git.mhagger@alum.mit.edu>

Extract a new function from `do_for_each_ref()`. It will be useful
elsewhere.
