Subject: [PATCH 2/8] lib/bitmap: change return types to bool where appropriate
Date: Fri,  1 Jul 2022 05:54:24 -0700	[thread overview]
Message-ID: <20220701125430.2907638-3-yury.norov@gmail.com> (raw)
In-Reply-To: <20220701125430.2907638-1-yury.norov@gmail.com>

Some bitmap functions return boolean results in int variables. Fix it
by changing return types to bool.
