Hi Song, This in turn depends on CONFIG_IKCONFIG_PROC for /proc/config.gz (not set for RHEL distro kernels). Is there a dynamic way to figure out CONFIG_KPROBES_ON_FTRACE support? Without looking into it very long, maybe test_klp_kprobe.c's call to register_kprobe() could fail with -ENOTSUPP and the test script could gracefully skip the test? Regards, -- Joe
