The security keys sysctls are already declared on its own file, just move the sysctl registration to its own file to help avoid merge conflicts on sysctls.c, and help with clearing up sysctl.c further. This creates a small penalty of 23 bytes: ./scripts/bloat-o-meter vmlinux.1 vmlinux.2 add/remove: 2/0 grow/shrink: 0/1 up/down: 49/-26 (23) Function old new delta init_security_keys_sysctls - 33 +33 __pfx_init_security_keys_sysctls - 16 +16 sysctl_init_bases 85 59 -26 Total: Before=21256937, After=21256960, chg +0.00% But soon we'll be saving tons of bytes anyway, as we modify the sysctl registrations to use ARRAY_SIZE and so we get rid of all the empty array elements so let's just clean this up now.
