Hello, two small patches two micro-optimize zs_object_copy(). The first one removes unneeded kunmap_atomic/kmap_atomic of dst page, when object that we copy belongs to two source pages. The seconds one is also trivial -- removes branching and (a bit) reduses the amount of work done by the function (double offsets calculations).
