If you want to add something, we could add to the beginning of this
function:

	/* Prevent ridiculously small sizes */
	if (size < PAGE_SIZE)
		return NULL;

to shut up Sashiko about overflows :-p

tracer_alloc_buffers() uses size of 1 for non-expanded buffers.

I'll test size just before 

  nr_pages = (size - sizeof(struct ring_buffer_cpu_meta)) /
  	(subbuf_size + sizeof(int));

Ack.
