Subject: [PATCH v2 2/5] fetch-pack: refactor add_haves()
Date: Tue,  4 May 2021 14:15:59 -0700	[thread overview]
Message-ID: <57c3451b2e36d003aa7fc398c644ce71ab668b5e.1620162764.git.jonathantanmy@google.com> (raw)
In-Reply-To: <cover.1620162764.git.jonathantanmy@google.com>

A subsequent commit will need part, but not all, of the functionality in
add_haves(), so move some of its functionality to its sole caller
send_fetch_request().
