Subject: [PATCH v2 0/2] mm/hugetlb: refactor sysfs/sysctl interfaces

From: Hui Zhu <zhuhui@...inos.cn>

The hugetlb.c file has grown significantly and become difficult to
maintain. This patch series extracts the sysfs and sysctl interface
code into separate dedicated files to improve code organization.

The refactoring includes:
- Patch 1: Extract sysfs interface into mm/hugetlb_sysfs.c
- Patch 2: Extract sysctl interface into mm/hugetlb_sysctl.c

No functional changes are introduced in this series. The code is moved
as-is, with only minor formatting adjustments for code style
consistency. This should make future maintenance and enhancements to
the hugetlb subsystem easier.

Testing: The patch series has been compile-tested and maintains the
same functionality as the original code.

Changelog:
v2:
According to the comments of David, remove the wrong copyright in
the file headers.
