Then you are either not not running a LITMUS^RT kernel, or you something went wrong during bootup and the /proc/litmus entry was not created (but I’ve never seen that fail before). Check your kernel message log for anything related to LITMUS^RT.

In particular, if you *are* running a LITMUS^RT kernel and are *not* seeing a /proc/litmus directory, then you should be able to find the error message from the following lines:

	litmus_dir = proc_mkdir("litmus", NULL);
	if (!litmus_dir) {
		printk(KERN_ERR "Could not allocate LITMUS^RT procfs entry.\n");
		return -ENOMEM;
	}

Are you perhaps accidentally launching the wrong kernels?

Are you 100% sure this is actually the kernel with the LITMUS^RT patch applied?
