Subject: [PATCH v39 28/42] LSM: Improve logic in security_getprocattr
Date: Fri, 15 Dec 2023 14:16:22 -0800	[thread overview]
Message-ID: <20231215221636.105680-29-casey@schaufler-ca.com> (raw)
In-Reply-To: <20231215221636.105680-1-casey@schaufler-ca.com>

The conditional in security_getprocattr() can be simplified
and made clearer. This change does that.
