Subject: [PATCH v2 07/43] refs.c: move read_ref_at to the common refs file
Date: Mon, 28 Sep 2015 18:01:42 -0400 [thread overview]
Message-ID: <1443477738-32023-8-git-send-email-dturner@twopensource.com> (raw)
In-Reply-To: <1443477738-32023-1-git-send-email-dturner@twopensource.com>
From: Ronnie Sahlberg <sahlberg@google.com>
Move read_ref_at() to the refs.c file since this function does not
contain any backend specific code.
