No, you're right. I had noticed just some minutes before reading your 
review that a made a typo.

I wanted to write: "In Documentation/vm/highmem.rst some kernel-doc 
comments are missing" instead for some unknown reason I wrote "the" in 
place of "some" :(

I'll fix it ASAP.

I have also read your review of the patch above. I agree with you that the 
"how" should be placed in the kernel-doc comments in the code. And I also 
agree that this patch should be part of a new version of a reorganized 
series.

I'll start working on your suggestions by tomorrow morning (it's midnight 
here in Italy).
