I just had to send a PR containing a single patch for 4.11, and it really feels like these simple fixes/improvements patches do not deserve a dedicated PR (not to mention that sometime I forget to send the PR and miss a release :-)). Now, regarding the peer-review thing, I'm not against reviewing a few simple patches from time to time, but I don't think I'll have time to review entire new drivers, and I guess that's the kind of thing your looking for :-/. > > - Should we force new submissions to be managed in that shared treee? > I think for initial submission a separate pull request for > approval-by-Dave is good (but we could do that with topic branches > too).
