Merge tag 'integrity-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity

Pull IMA updates from Mimi Zohar:
 "New is IMA support for measuring kernel critical data, as per usual
  based on policy. The first example measures the in memory SELinux
  policy. The second example measures the kernel version.

  In addition are four bug fixes to address memory leaks and a missing
  'static' function declaration"
