Hello again Luis.

Another thing you might consider is to  align
multiple line statements to the appropriate
open parenthesis.

This is in a commented out block, but this
would look better like:

		printk_ratelimited("format",
				   args...);

cvm_oct_get_buffer_ptr returns a void pointer
so it doesn't need a cast.

a possible fix is just to remove the cast

		pskb = cvm_oct_get_buffer_ptr(work->packet_ptr) - sizeof(void *);

If the cast type above to a ** is to be believed,
maybe this should be prefetch(*pskb)

If you do these, they should be separate patches.
