All,
I have a suspicion this will help my efforts increasing the IOPS
ability of mdraid  in 10-12 NVMe drive  per raid group situations.

Pure neophyte question, which I apologize for in advance, how can I
test this?   Does this end up in  a 5.15 release candidate kernel?

It's queued up to go into Linus's tree before -rc1, so should be in
5.15-rc1 for you to test.

I want to make contributions wherever I can, as I have hardware and
needs, so I can act as a performance validator within reason.   I know
I can't make contributions as a developer, but I'm willing to
contribute in areas where our goals are in alignment and this appears
to be one.

Testing is definitely valuable, particularly for something like this! So
please do test -rc1 and report back your findings.
