Subject: [PATCH v5 24/38] SELinux: Remove unused selinux_is_enabled
Date: Mon, 26 Nov 2018 15:45:05 -0800
Message-ID: <8b7b3c7e-acd1-cd0f-95a3-02f09bfbfc96@schaufler-ca.com> (raw)
In-Reply-To: <50db058a-7dde-441b-a7f9-f6837fe8b69f@schaufler-ca.com>

There are no longer users of selinux_is_enabled().
Remove it. As selinux_is_enabled() is the only reason
for include/linux/selinux.h remove that as well.
