[PATCH v3 -next 00/15] sysctl: move sysctls from vm_table into its own files

From: Kaixiong Yu
Date: Thu Oct 10 2024 - 10:11:58 EST


This patch series moves sysctls of vm_table in kernel/sysctl.c to
places where they actually belong, and do some related code clean-ups.
After this patch series, all sysctls in vm_table have been moved into its
own files, meanwhile, delete vm_table.

All the modifications of this patch series base on
linux-next(tags/next-20241010). To test this patch series, the code was
compiled with both the CONFIG_SYSCTL enabled and disabled on arm64 and
x86_64 architectures. After this patch series is applied, all files
under /proc/sys/vm can be read or written normally.

Changes in v3:
- change patch1~10, patch14 title suggested by Joel Granados
- change sysctl_stat_interval to static type in patch1
- add acked-by from Paul Moore in patch7
- change dirtytime_expire_interval to static type in patch9
- add acked-by from Anna Schumaker in patch11

Changes in v2:
- fix sysctl_max_map_count undeclared issue in mm/nommu.c for patch6
- update changelog for patch7/12, suggested by Kees/Paul
- fix patch8, sorry for wrong changes and forget to built with NOMMU
- add reviewed-by from Kees except patch8 since patch8 is wrong in v1
- add reviewed-by from Jan Kara, Christian Brauner in patch12
