Good idea. I will also consider implementing this kind of checks to to my lzy
tool box [1] or hkml [2].

Thank you for calling out this, Lorenzo.

Lian, please do as Lorenzo kindly asked, from the next revision. You don't
need to add those recipients to all the patches if you worry their inbox
volumes. But do ensure adding them to at least patches that modifies
khugepaged.h and khugepaged.c, and the cover letter.

If it is cumbersome, consider using 'hkml patch format' [3]. It does that (run
get_maintainer.pl and add recipients to each patch and the coverletter) for its
users.
