Subject: move exit_ptrace() from forget_original_parent() to do_exit()
From: Oleg Nesterov <oleg@xxxxxxxxxx>

By discussion with Roland.

Call exit_ptrace() from do_exit(), no need to delay this call until
forget_original_parent().

If we ever change exit_ptrace() to do the blocking calls, it makes
sense to move it after exit_signals().
