Hi, This is v4 of my nvme patches.
This is mostly changes related to Beatas review (thanks again). Some of the comments led to some refactoring, so the changes trickled down through the series. That is why the backport diff show a lot of changes. I dropped 'nvme: allow completion queues in the cmb' from the series as it is not well tested. And there are no real users for this right now. p2p might use it, but the support can be added if/when needed. I ran into some trace event names clashing with the nvme block driver, so I have included a patch that changes all trace events to use the `nvme_dev` prefix instead. I split 'nvme: add support for the get log page command' up to move adding of the temperature threshold feature to its own commit.
