I think I have told you many time now and you are missing to understand
few basic stuff. So I suggest to give
`Documentation/process/submitting-patches.rst`
under the kernel source a read and especially the section
`The canonical patch format`

Ideally this patch should have been v5 as you added Hanjun's Ack
Also "v1->v2->v3: Modify the commit log description" makes no sense.

The changelog should list all the deltas like:
v4->v5:
	- <blah3 blah3>
v3->v4:
	- <blah2 blah2>
v2->v3:
	- <blah1 blah1>
v1->v2:
	- <blah blah>

Anyways, it is only for your learning and future references.
