There's currently two options of merging this, either all at once or first only patch 1 and then the additional patches per subsystem until finally the last patch can remove inb()/outb() and friends when HAS_IOPORT is unset. Thanks, Niklas

It's probably too late now to squeeze patch 1 into linux-6.3 as a late preparation patch for the rest of the series in 6.4. It would be good if you could respin that patch separately anyway, so I can add it to the asm-generic tree and make sure we get it ready for the next merge window. Arnd

I'm currently going through the patches one by one incorporating comments. I fear the split of the USB patch as well as the suggestions for video might take a bit of time, so if you prefer I could also send just an updated patch 1 separately. How would I do this cleanly? Send as v4 without(?) a cover letter and add a Note after the '---'? Thanks, Niklas

In case you need multiple versions, I would suggest you continue counting at v4 independently for both the preparation patch and the rest of the series. Arnd

You only sent me this patch. If there are in-set dependencies, you need to send everyone the whole set so that we can organise a suitable merge strategy between us. I'll revert the patch for now. -- Lee Jones [李琼斯]

As far as I know sadly it's not possible to Cc everyone for such treewide series because the recipient list will hit the limits supported by some systems and mails get dropped which sucks even more. Maybe this can be solved in the future though, Konstantin Ryabitsev actually reached out because I mentioned that I tried using b4 prep / b4 send but couldn't exactly because it only supports a global recipient list. Thanks, Niklas

Through an immutable branch, else all dependencies have to wait for v6.5? Gr{oetje,eeting}s, Geert

Sure, will do. I suspect that there will still be something left behind that doesn't make it into 6.4, so the final bit (dropping broken inb/outb implementations) will have to be 6.5 material anyway, but at least we can aim on getting most of it into 6.4.
