Move sysctl check into debugging section and don't make it default y (9e94cd32) · Commits · 戴 / test

I noticed that sysctl_check.o was the largest object file in a allnoconfig build in kernel/*. 36243 0 0 36243 8d93 kernel/sysctl_check.o This is because it was default y and && EMBEDDED. But I don't really see a need for a non kernel developer to have their sysctls checked all the time. So move the Kconfig into the kernel debugging section and also drop the default y and the EMBEDDED check. Signed-off-by:
