Subject: [PATCH 02/10] lib/bitmap: change return types to bool where appropriate
Date: Wed,  6 Jul 2022 10:42:45 -0700	[thread overview]
Message-ID: <20220706174253.4175492-3-yury.norov@gmail.com> (raw)
In-Reply-To: <20220706174253.4175492-1-yury.norov@gmail.com>

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