Hello Sakari,
I can definitely include other changes, but then it will be many different
types of changes into a single patch. Will that be okay?
I was planning to address one issue per patch as I think the volume of
change is going to be high. I mentioned that in the notes section of the patch
message.
Let me know if you still suggest I combine those.
Thank you,
deepak.
