Sorry for my poor English. I never got this rule. 

Which one is a "substantially" right? Can you give me an example?

I need to understand how you'd write this to satisfy the above rule.

like this:

memcpy(lldev->tre_ring + lldev->tre_write_offset, &tre->tre_local[0],
       TRE_SIZE);

or

memcpy(lldev->tre_ring + lldev->tre_write_offset,
       &tre->tre_local[0], TRE_SIZE);

or

memcpy(lldev->tre_ring + lldev->tre_write_offset, &tre->tre_local[0],
							   TRE_SIZE);

or

memcpy(lldev->tre_ring + lldev->tre_write_offset,
	&tre->tre_local[0], 
	TRE_SIZE);
