Subject: [RFC PATCH] selinux: runtime disable is deprecated, add some ssleep() discomfort
Date: Tue, 02 Jun 2020 08:47:58 -0400
Message-ID: <159110207843.57260.5661475689740939480.stgit@chester> (raw)

We deprecated the SELinux runtime disable functionality in Linux
v5.6, add a five second sleep to anyone using it to help draw their
attention to the deprecation.
