- Plug the ptrace_may_access() race against a concurrent exec() which
allows to pass the check before the target's process transition in
exec() by taking a read lock on signal->ext_update_lock.
- A large set of cleanups and enhancement to the futex selftests. The
bulk of changes is the conversion to the kselftest harness.

Pull futex updates from Thomas Gleixner:
"A set of updates for futexes and related selftests:
- Plug the ptrace_may_access() race against a concurrent exec() which
allows to pass the check before the target's process transition in
exec() by taking a read lock on signal->ext_update_lock.
- A large set of cleanups and enhancement to the futex selftests. The
bulk of changes is the conversion to the kselftest harness"
