I guess this series are patches against for user-space blktrace tool
https://git.kernel.dk/?p=blktrace.git
And the updates depends on the kernel side update of your series;
https://lore.kernel.org/all/20250909110611.75559-1-johannes.thumshirn@wdc.com/
Right?
I'm not sure how the blktrace tool development is managed, but please make
sure this series is not for the kernel. (ah, both has blktrace: tag, hmmm)
Thank you,
