This still does not explain WHY you need to do that. 'Preparation' is a
pretty useless information.

What is the actual reason for this? Just because PKS information feels
better that way?

Also what is PKS information? Changelogs have to make sense on their own
and not only in the context of a larger series of changes.

  While at it change all usage sites to consistently use the variable
  name 'irq_state'.

Or something like that. See Documentation/process/...

Thanks,
