Patch one is a preparation patch from Sagi and caches the nvme_ctrl in the nvme_request. This is not only useful for the tracepoints but for further development as well.
The second patch adds the controller IDs and if applicable the disk name to the tracepoints so we can distinguish between the individual controllers and disks. The patches are relative to the nvme-4.19 branch.
