[GIT PULL] SELinux patches for v5.12

[Paul Moore]

Hi Linus,

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 below:

- 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.

Thanks,
-Paul
