signal: move show_unhandled_signals sysctl to its own file
The show_unhandled_signals sysctl is the only sysctl for debug left on kernel/sysctl.c. We've been moving the syctls out from kernel/sysctl.c so to help avoid merge conflicts as the shared array gets out of hand. This change incurs simplifies sysctl registration by localizing it where it should go for a penalty in size of increasing the kernel by 23 bytes, we accept this given recent cleanups have actually already saved us 1465 bytes in the prior commits. ./scripts/bloat-o-meter vmlinux.3-remove-dev-table vmlinux.4-remove-debug-table add/remove: 3/1 grow/shrink: 0/1 up/down: 177/-154 (23) Function old new delta signal_debug_table - 128 +128 init_signal_sysctls - 33 +33 __pfx_init_signal_sysctls - 16 +16 sysctl_init_bases 85 59 -26 debug_table 128 - -128 Total: Before=21256967, After=21256990, chg +0.00% Reviewed-by: Joel Granados <j.granados@samsung.com> Signed-off-by: Luis Chamberlain <mcgrof@kernel.org>
