You could find inspiration in tools/testing/selftests/livepatch/test-livepatch.sh, see load_lp $MOD_REPLACE replace=0 vs. load_lp $MOD_REPLACE replace=1 You could more or less copy the "multiple livepatches" and "atomic replace livepatch" self-tests. The new tests would check the "stack_order" sysfs value instread of checking whether /proc/cmdline and /proc/meminfo are livepatched. Best Regards, Petr
