Subject: [PATCH] smack: clean up smack_enabled to be more readable
Date: Wed, 3 Nov 2021 07:31:31 +0000	[thread overview]
Message-ID: <20211103073131.GA15173@raspberrypi> (raw)

The smack_enabled is only set to 0, 1. So changing type of smack_enabled 
as bool may make relevant routine be more readable.
