This misses another file: include/linux/hugetlb_inline.h

The current HUGETLB block is:

HUGETLB SUBSYSTEM
M:	Muchun Song <muchun.song@xxxxxxxxx>

R:	David Hildenbrand <david@xxxxxxxxxx>

F:	mm/hugetlb_vmemmap.h

And your suggestion is:

but:

$ git ls-files include/linux/hugetlb*
include/linux/hugetlb.h
include/linux/hugetlb_cgroup.h
include/linux/hugetlb_inline.h

so maybe:

F:	include/linux/hugetlb*

or maybe:

X:	arch/**/*hugetlb*
F:	**/*hugetlb*

and remove a lot of other entries

$ git ls-files -- '**/*hugetlb*'
