Subject: selftests/landlock: Add user space tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Test all Landlock system calls, ptrace hooks semantic and filesystem
access-control with multiple layouts.

Test coverage for security/landlock/ is 93.6% of lines.  The code not
covered only deals with internal kernel errors (e.g. memory allocation)
and race conditions.
