Merge tag 'sysctl-6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl
Pull sysctl updates from Joel Granados: - Move vm_table members out of kernel/sysctl.c All vm_table array members have moved to their respective subsystems leading to the removal of vm_table from kernel/sysctl.c. This increases modularity by placing the ctl_tables closer to where they are actually used and at the same time reducing the chances of merge conflicts in kernel/sysctl.c. - ctl_table range fixes Replace the proc_handler function that checks variable ranges in coredump_sysctls and vdso_table with the one that actually uses the extra{1,2} pointers as min/max values. This tightens the range of the values that users can pass into the kernel effectively preventing {under,over}flows. - Misc fixes Correct grammar errors and typos in test messages. Update sysctl files in MAINTAINERS. Constified and removed array size in declaration for alignment_tbl * tag 'sysctl-6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl: (22 commits) selftests/sysctl: fix wording of help messages selftests: fix spelling/grammar errors in sysctl/sysctl.sh MAINTAINERS: Update sysctl file list in MAINTAINERS sysctl: Fix underflow value setting risk in vm_table coredump: Fixes core_pipe_limit sysctl proc_handler sysctl: remove unneeded include sysctl: remove the vm_table sh: vdso: move the sysctl to arch/sh/kernel/vsyscall/vsyscall.c x86: vdso: move the sysctl to arch/x86/entry/vdso/vdso32-setup.c fs: dcache: move the sysctl to fs/dcache.c sunrpc: simplify rpcauth_cache_shrink_count() fs: drop_caches: move sysctl to fs/drop_caches.c fs: fs-writeback: move sysctl to fs/fs-writeback.c mm: nommu: move sysctl to mm/nommu.c security: min_addr: move sysctl to security/min_addr.c mm: mmap: move sysctl to mm/mmap.c mm: util: move sysctls to mm/util.c mm: vmscan: move vmscan sysctls to mm/vmscan.c mm: swap: move sysctl to mm/swap.c mm: filemap: move sysctl to mm/filemap.c ...
