... and please snip long replies.

Scrolling down past lots of un-reviewed code and/or past the end of
the last review comment is a waste of people's time.  Thanks.

Hm. Right. I thought that leaving whole patch there when just adding
ack or reviewed-by gives full information as to which exact patch
version was reviewed. But I admit scrolling can be annoying - besides,
the send/receive time in quote can probably be used to track the excat
version which was reviewed. So point taken. Thanks.

Best Regards

While you're at it, please remove "MFD".

Maybe replace with 'core' or something?

We can see that by the struct name.
