Merge tag 'selinux-pr-20180814' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull SELinux updates from Paul Moore:
 "There are 16 patches in here but really only one that is of any
  significance. That one patch is by nixiaoming and fixes a few places
  where we were not properly cleaning up dentry and inode objects in the
  selinuxfs error handling code. The rest are either printk->pr_*
  conversions, constification tweaks, and a minor tweak to MAINTAINERS.

  Everything passes the selinux-testsuite and looks to merge cleanly
  against your master branch"
