Every two months I see one of my or other folks around my area patch which is being changed in incorrect way between mailing list and Git. Change is done because: 1. Patch did not apply cleanly (a lot of simultaneous work, so base is obviously old the moment the maintainer applies such patch) 2. Maintainer tried to resolve that by applying to the correct base (so followed your process) and then did git rebase or cherry pick to his final development branch. 3. Maintainer is overloaded and has no time to investigate whether rebase/cherry-pick from above is truly correct, except building the code, so every two months result of such rebase is wrong. This is a real issue because it is very difficult to spot - your commit is applied, but you never verify whether is applied THE SAME way and maintainer thinks everything was applied cleanly. If (1) happens and patch does not apply, the solution is to ask the contributor to rebase. So sorry, but the proper base rather encourages risky patch merging/rebasing, instead of pushing the rebase problem to the person actually knowing the patch and having hardware to validate it.
