Hi,
the code looks good, though it might make sense to simply integrate the
check into ptrace08. Just 6 extra lines in the existing test should
achieve the same coverage.
It also seems the bug existed long before the CVE 2018-1000199 fix
because the test fails on vulnerable kernels as well.
Anyway, if you prefer to keep the patch as is:

I would like to avoid triggering the "your system may be vunerable"
messages on fixed kernel, hence the separate test.
