Linus rejected your patch for reasons that had absolutely nothing to do with USB backport support issues. Rather, the kernel version tracking was rejected because Linus wants that functionality added in 2.5 in a careful manner. I'm not saying your patch wasn't perfect and thoughtful. I thought your patch looked great, but I don't control kernel checkins. Regarding the USB backport support, the usbd and kernel policy stuff that David Brownell and others develops works great for that environment. There are several important functional holes in the backport. One of them being in the USB Storage area. If I understand this correctly, these are holes that are intrinsic to the older kernel and are not easily worked around. All that to say that noone using a 2.2 kernel is going to be in USB nirvana anyhow, though it works quite well. Be assured, I'll be delighted when Linus accepts your patch and modutils can support kernel version tracking so that modutils can better support and handle ABI changes. We are all just rolling with Linus. He is calling the shots, here. I appreciate you getting this functional change into 2.4.2 so that USB users in the 2.4.0 series can use hotplugging. I'll test your patch immediately.
