Let's not over complicate things. There aren't that many changes typically in a cycle, so we can deal with it. I'd expect most changes would not collide as docbook comments and code changes are separated somewhat. I'd like a git branch for this. I'll keep it separate until -rc6 or so and then you can rebase things then if merging becomes a problem. Or we can drop any problematic patches. > 2) Split method 1 into stages (one patch per file for each stage). > Examples of some possible stages are: > - white space fixes > - syntax fixes > - incorrect argument list fixes > - incorrect return type fixes > - incorrect return value fixes > - incorrect behavior description fixes > - confusing behavior description fixes > pro: it would be easier to review patches for many of the stages > con: a lot more patches > con: maybe difficult to handle conflicts with code patches > con: maybe difficult to rework patches for review comments (changes > for an earlier stage are likely to impact a patch for a later > stage) > > 3) Do one patch series to remove all docbook function header documentation. > Do a second patch series to add the updated docbook function header > documentation.

Is this going to impact your work?
