Alan - it seems you're missing the whole point.
The thing I objected to, in the VERY BEGINNING in this thread, i the fact that the thing was done in such a way that it's basically impossible to support the old/new ABI at all! Let me quote that second email:
"That commit seems to _on_purpose_ try to avoid at all cost being compatible. It not only removes some old entry-points, it literally re-numbers all the ioctl numbers as it does so, apparently entirely in order to just make it difficult to have some libdrm that can handle both versions."
So it's not a "before the patch went upstream" issue. The same issue exists _after_ the patch went upstream.
The way this was done, it's apparently basically impossible for the Fedora people to push out packaged that support both the old and the new kernel.
Alan, if this had been done in a way that allowed that whole old/new ABI that you mention to work, I wouldn't have been complaining so much!
In other words - I've not been complaining about updating the ABI. I've been complaining about doing it in such a way that it's near impossible to go back-and-forth, because the very thing you suggest was made way way harder than it should be.
