[PATCH v2 1/2] MAINTAINERS: cover all hugetlb headers under HUGETLB SUBSYSTEM

[PATCH v2 1/2] MAINTAINERS: cover all hugetlb headers under HUGETLB SUBSYSTEM

[Enze Li]

The HUGETLB SUBSYSTEM F: entries list include/linux/hugetlb.h
explicitly, but other hugetlb headers are not covered, so
get_maintainer.pl does not attribute them to the hugetlb maintainers.

Enumerating headers by hand is also fragile: any header not listed (such
as hugetlb_cgroup.h) falls outside the subsystem.  Joe Perches suggested
using a glob F: entry, which covers all current and future hugetlb
headers in one line and avoids the gap.

Changes in v2:
- Adopt the glob pattern "F: include/linux/hugetlb*" as suggested by
  Joe Perches.
- Drop the Acked-by: tags from Muchun Song and David Hildenbrand, since
  the patch content changed.

[PATCH v2 2/2] mm/hugetlb_cgroup: add trailing #endif comment for include guard

[Enze Li]

The final #endif that closes the _LINUX_HUGETLB_CGROUP_H include guard
is left without a comment.  Add the macro name to the comment for
consistency and easier navigation.
