Subject: [PATCH v2 7/7] maple_tree: refine mab_calc_split function
Date: Wed, 21 Dec 2022 14:00:58 +0800 [thread overview]
Message-ID: <20221221060058.609003-8-vernon2gm@gmail.com> (raw)
In-Reply-To: <20221221060058.609003-1-vernon2gm@gmail.com>
Invert the conditional judgment of the mid_split, to focus
the return statement in the last statement, which is easier
to understand and for better readability.
