Hi David,

It may have escaped your notice that I was shepherding a newer version
of Tanjore's original patchset through the nvme lists already. Please
look at version 5 here (I am working on version 6 currently).

https://lore.kernel.org/linux-nvme/20240129181953.1183084-1-jallison@ciq.com/

As your work is very similar (although has some of the same problems
that people already asked me to fix in earlier versions of the code)
maybe we can collaborate on getting a unified version of this work
reviewed.

Please take a look at the link above, and see if we can merge our efforts.

Thanks !
