Subject: BKL use in ptrace


Hi,

ptrace has this comment/BKL use:

        /*
         * This lock_kernel fixes a subtle race with suid exec
         */
        lock_kernel();

But unless I'm blind I don't see execve actually getting the BKL
anywhere. So is this comment outdated or misleading (is the race with exit?)
or is there a bug?

Thanks,
-Andi
