Pull selinux updates from Paul Moore:
"We've got a good handful of patches for SELinux this time around; with
everything passing the selinux-testsuite and applying cleanly to your
tree as of a few minutes ago. The highlights are:
- Add support for labeling anonymous inodes, and extend this new
support to userfaultfd.
- Fallback to SELinux genfs file labeling if the filesystem does not
have xattr support. This is useful for virtiofs which can vary in
its xattr support depending on the backing filesystem.
- Classify and handle MPTCP the same as TCP in SELinux.
- Ensure consistent behavior between inode_getxattr and
inode_listsecurity when the SELinux policy is not loaded. This
fixes a known problem with overlayfs.
- A couple of patches to prune some unused variables from the SELinux
code, mark private variables as static, and mark other variables as
__ro_after_init or __read_mostly"

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.
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.
