This is part of the general push to deprecate register_sysctl_paths and register_sysctl_table. The old way of doing this through register_sysctl_base and DECLARE_SYSCTL_BASE macro is replaced with a call to register_sysctl_init. The 5 base paths affected are: "kernel", "vm", "debug", "dev" and "fs". We remove the register_sysctl_base function and the DECLARE_SYSCTL_BASE macro since they are no longer needed. In order to quickly acertain that the paths did not actually change I executed `find /proc/sys/ | sha1sum` and made sure that the sha was the same before and after the commit. We end up saving 563 bytes with this change: ./scripts/bloat-o-meter vmlinux.0.base vmlinux.1.refactor-base-paths add/remove: 0/5 grow/shrink: 2/0 up/down: 77/-640 (-563) Function old new delta sysctl_init_bases 55 111 +56 init_fs_sysctls 12 33 +21 vm_base_table 128 - -128 kernel_base_table 128 - -128 fs_base_table 128 - -128 dev_base_table 128 - -128 debug_base_table 128 - -128 Total: Before=21258215, After=21257652, chg -0.00% [mcgrof: modified to use register_sysctl_init() over register_sysctl() and add bloat-o-meter stats] Signed-off-by: Joel Granados <j.granados@samsung.com> Signed-off-by: Luis Chamberlain <mcgrof@kernel.org> Tested-by: Stephen Rothwell <sfr@canb.auug.org.au> Acked-by: Christian Brauner <brauner@kernel.org>
