Hello Zack,

Thank you for reviewing my patch's documentation and commit messages.
Almost all the things I wanted to say were expressed and I think that
is very nice.

Also, Rafal and Paul, thank you for reviewing my patch's documentation
and commit messages.

I will soon prepare a new version set of patches with these remarks
applied.
