Hi Rafael,
Just a quick note: I agree with Zhongqiu's feedback and the commit
message needs a fix.
Regarding merging the patches, the issue with maintainers picking up
fixes is that the series will break the clang/llvm build without them.
So the maintainers need to either merge the patches (and the series be
rebased on top of them) or merge the series as a unit. Perhaps since
the patches align, merge conflicts won't happen, so maintainers
merging and landing the series is okay. I don't have the experience to
know.
Thanks,
Ian
