This changelog including the subject line still sucks.

Q: How is the counter change related subject line?
A: Not at all.

Q: Why do we need to change this to a counter?
A: Because

Q: What problem is being solved?
A: Dunno

Q: Why do we need the export?
A: HyperV having certain circumstances

Summary: The changelog is useless

The patch wants to be split in two parts:

1) Make the counter change and explain why the current mode is not
   sufficient and what kind of problem can be solved

2) Export the functions with a proper explanation why.

Thanks,
