Definitely can do, I'm not sure how to interpret the data in this - is there anything specific you're looking for?  Would love to not just pass the information on but also learn from this.

Most of the information in debugfs is needed. It's easier to capture it all than to only request for the many attributes that are needed.

I'm not sure there is any better documentation available for these attributes than the information in the source file block/blk-mq-debugfs.c.

Thanks,

Bart.
