Following the extraction of sysfs code, this patch moves the sysctl interface implementation into a dedicated file to further improve code organization and maintainability of the hugetlb subsystem. The following components are moved to mm/hugetlb_sysctl.c: - proc_hugetlb_doulongvec_minmax() - hugetlb_sysctl_handler_common() - hugetlb_sysctl_handler() - hugetlb_mempolicy_sysctl_handler() (CONFIG_NUMA) - hugetlb_overcommit_handler() - hugetlb_table[] sysctl table definition - hugetlb_sysctl_init() The hugetlb_internal.h header file is updated to declare the sysctl initialization function with proper #ifdef guards for configurations without CONFIG_SYSCTL support. The Makefile is updated to compile hugetlb_sysctl.o when CONFIG_HUGETLBFS is enabled. This refactoring reduces the size of hugetlb.c and logically separates the sysctl interface from core hugetlb management code. MAINTAINERS is updated to add new file hugetlb_sysctl.c. No functional changes are introduced; all code is moved as-is from hugetlb.c with consistent formatting.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
