Subject: [PATCH 15/15] do_for_each_ref(): only iterate over the subtree that was requested
Date: Tue, 10 Apr 2012 07:30:27 +0200	[thread overview]
Message-ID: <1334035827-20331-16-git-send-email-mhagger@alum.mit.edu> (raw)
In-Reply-To: <1334035827-20331-1-git-send-email-mhagger@alum.mit.edu>

From: Michael Haggerty <mhagger@alum.mit.edu>
