Hi Thomas,

Thank you for submitting this patch, but it really doesn't add any
value to the SELinux code so I'm not going to merge it at this time.
If you would like to contribute to SELinux there are a number of
issues open on our GitHub page that you could look into resolving,
those patches would be very welcome.
