Re: [LTP] [PATCH] syscalls/ptrace10: Add new regression test

From: Martin Doucha

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:
