Indeed. The reason we have "clear_page()" is not because the value we're writing is constant - that doesn't really help/change anything at all. We could have had a "fill_page()" that sets the value to any random byte, it's just that zero is the only value that we really care about. So the reason we have "clear_page()" is because the *size* and *alignment* is constant and known at compile time, and unlike the value you write, that actually matters. So "memzero()" would never really make sense as anything but a syntactic wrapper around "memset(x,0,size)".
