Subject: [PATCH v5 03/16] Add initial support for many promisor remotes
Date: Tue, 9 Apr 2019 18:11:03 +0200 [thread overview]
Message-ID: <20190409161116.30256-4-chriscool@tuxfamily.org> (raw)
In-Reply-To: <20190409161116.30256-1-chriscool@tuxfamily.org>
From: Christian Couder <christian.couder@gmail.com>
The promisor-remote.{c,h} files will contain functions to
manage many promisor remotes.
We expect that there will not be a lot of promisor remotes,
so it is ok to use a simple linked list to manage them.
