Subject: [PATCHv2 5/5] submodule: submodule_move_head omits old argument in forced case
Date: Wed, 27 Dec 2017 14:57:05 -0800	[thread overview]
Message-ID: <20171227225705.73235-6-sbeller@google.com> (raw)
In-Reply-To: <20171227225705.73235-1-sbeller@google.com>

When using hard reset or forced checkout with the option to recurse into
submodules, the submodules need to be reset, too.

It turns out that we need to omit the duplicate old argument to read-tree
in all forced cases to omit the 2 way merge and use the more assertive
behavior of reading the specific new tree into the index and updating
the working tree.
