And then there is the Bluetooth SCO change which I agree was
borderline and I should have pushed back on.

so this is the statement, I sent Dave to explain why that change was in
there:

---
For the btusb driver this adds the promised SCO support. The btusb
driver is a new driver and will eventually replace hci_usb. Adding SCO
support was the last missing piece. All distributions are using the
hci_usb driver at the moment and you can only select one of them. So
this can't introduce any regression. With this change the distributions
are now able to select the new driver if they really want to.

Was this absolutely needed after -rc3. Of course not. No questions asked
about it. So why did it ended up in there?

Almost everybody is using the hci_usb driver and that one has issues
that are beyond fixable. So the btusb is its replacement and with this
change it became a real alternate solution. For me this is a new driver
that would allow people to use it in case hci_usb gives them a hard time
and falls over again. And fixing hci_usb is not an option. A lot of
people tried it and they failed. I think the last one was Pavel a month
ago. This is why I re-wrote the whole beast from scratch.

So that is my excuse why I thought this would be good choice to push it
to Dave. No more excuses and no new drivers after the merge window. At
least not from me.

one of thr goals of the new release approach was to make releases frequently enough that it's not a big deal to miss a merge window, you only have to wait a couple of months (rather then a couple of years under the old model).

while I don't see a bit problem with drivers going in for previously unsupported hardware (at least since I custom compile my kernels with all unnessasary drivers disabled, so I wouldn't even try to compile them ;-) it doesn't hurt much, either as a user, or for you as a developer (as you note above) to go ahead and delay till the next merge window.

the benifits of delaying are that the changes in the -rc cycle are clearer and smaller. this should make the progress towards the release more obvious, and avoid distractions like the one that started this thread. yes, this will make the -rc1/-rc2 even bigger as there is more stuff going in, but it looks like that is being handled well (in part thanks to the preview that -next is providing)

so as a user/tester I want to thank you for being so willing to delay new stuff for the next merge window, may others learn to follow your example.
