Subject: [GIT PULL] integrity subsystem updates for v5.12

Hi Linus,
  
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.

[FYI: Stephen is carrying a manual merge of the pidfd tree with the
integrity tree.]

thanks,

Mimi
