In fact the thread was more than ten-deep so I probably fell asleep. ..
Last I recall, Greg was vehemently opposed to having direct path access by device number in sysfs, but many other people saw benefit.
Myself (the originator), I simply decided that my sysfs access code has to work with older kernels too, so for now I'm just doing a brute force tree search to find things in sysfs. I did get the code size down smaller for it, but it's still a pain.
When the direct access feature goes in, I'll just change my code to try it first, and then still fall back to the tree search method on failure.

Good!
