Sorry, are you sure? The child process is not running when ptrace() is called,
and this holds even for PTRACE_SWITCH_MM (check ptrace_check_attach()).
So, the child process is not running and activate_mm cannot be called (maybe I
do not understand activate_mm, but it's simply switch_mm, that is called by
schedule, so I think I guessed right).
