I'll double check again, but from a quick look, looks like yours is the
better version.

The reason it's messy is not the code in for-4.6/drivers branch, it's
the amount of activity in the post merge window time for the last
release. And that's why it was messy in the 4.5 merge window as well,
the post merge changes for NVMe, not the history of the patches in the
merge window. But you already know that. It's not two different groups
of people, it's the same people...

Agree, it's not going to be an issue going forward.
