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,
