Subject: [PATCH v5 07/27] refs: add methods for reflog
Date: Thu, 18 Feb 2016 00:17:30 -0500	[thread overview]
Message-ID: <1455772670-21142-8-git-send-email-dturner@twopensource.com> (raw)
In-Reply-To: <1455772670-21142-1-git-send-email-dturner@twopensource.com>

In the file-based backend, the reflog piggybacks on the ref lock.
Since other backends won't have the same sort of ref lock, ref backends
must also handle reflogs.
