Commit0619f0f5e3("selinux: wrap selinuxfs state") triggers a BUG when SELinux is runtime-disabled (i.e. systemd or equivalent disables SELinux before initial policy load via /sys/fs/selinux/disable based on /etc/selinux/config SELINUX=disabled). This does not manifest if SELinux is disabled via kernel command line argument or if SELinux is enabled (permissive or enforcing). Before: SELinux: Disabled at runtime. BUG: Dentry 000000006d77e5c7{i=17,n=null} still in use (1) [unmount of selinuxfs selinuxfs] After: SELinux: Disabled at runtime.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
