when CONFIG_TEST_SYSCTL=y, there is no "/sys/module/test_sysctl/" when CONFIG_TEST_SYSCTL=m, checking /sys/module/test_sysctl/ is before kernel module loading
you'll get below error message root@intel-x86-64:/tmp/sysctl# ./sysctl.sh Checking production write strict setting ... ok ./sysctl.sh: /sys/module/test_sysctl/ not present You must have the following enabled in your kernel:
This patch will fix this issue. when CONFIG_TEST_SYSCTL=y, it has no chance to check "/sys/module/test_sysctl/" when CONFIG_TEST_SYSCTL=m, it will load kernel module first before checking sys interface.
