As I see it, we need the following changes.

utrace:

        - utrace_control(SINGLESTEP) calls get_user_pages() under
          spin_lock()

ptrace:

        - stacked VFORK_DONE event, finish ptrace_report_clone().
          The fix must be trivial, but every time I am trying to
          complete this I understand I should do this with a fresh
          head ;)

        - PTRACE_SYSEMU/PTRACE_SYSEMU_SINGLESTEP
          should be simple...

        - stacked JCTL events. Oh. I hope this will not be too hard
          to do something simple and "not too buggy" for now.

        - ptrace_check_attch().
          Must be simple, but I am starting to think I have a blind
          spot here.

        - simple cleanups, may be more comments.

Anything else?

Oleg.
