Subject: [RFC PATCH v1 1/6] stash: mark `i_tree' in reset_tree() const
Date: Tue,  5 May 2020 12:48:44 +0200	[thread overview]
Message-ID: <20200505104849.13602-2-alban.gruin@gmail.com> (raw)
In-Reply-To: <20200505104849.13602-1-alban.gruin@gmail.com>

As reset_tree() does not change the value pointed by `i_tree', and that
it will be provided with `the_hash_algo->empty_tree' which is a
constant, it is changed to be a pointer to a constant.
