Subject: [GSoC][PATCH 1/6 v2] submodule--helper: introduce for_each_submodule_list
Date: Tue, 27 Jun 2017 04:41:03 +0530
Message-ID: <20170626231108.23640-1-pc44800@gmail.com> (raw)
In-Reply-To: <CAME+mvUrr8EA-6jbCZdpB7dMZ5CN3RyY7yoRoUBoiZw=sH6Ysw@mail.gmail.com>

Introduce function for_each_submodule_list for using it
in the later patches, related to porting submodule
subcommands from shell to C.
This new function is also used in ported submodule subcommand
init.
