    ptrace children revamp · f470021a
    Roland McGrath authored
    ptrace no longer fiddles with the children/sibling links, and the
    old ptrace_children list is gone.  Now ptrace, whether of one's own
    children or another's via PTRACE_ATTACH, just uses the new ptraced
    list instead.
    
    There should be no user-visible difference that matters.  The only
    change is the order in which do_wait() sees multiple stopped
    children and stopped ptrace attachees.  Since wait_task_stopped()
    was changed earlier so it no longer reorders the children list, we
    already know this won't cause any new problems.
