Hi Djalal,

Thank you for your work on this!

What purpose does this securelevel-like property ("Once set, this value
can not be changed.") serve here?  I think this mode 2 is needed, but
without this extra property, which is bypassable by e.g. explicitly
loaded kernel modules anyway (and that's OK).

I'm sorry if this has been discussed before.
