The sample_fprobe puts a fprobe on kernel_clone() by default. This dump stack and some called address info at the function entry and exit. The sample_fprobe.ko gets 2 parameters. - symbol: you can specify the comma separated symbols or wildcard symbol pattern (in this case you can not use comma) - stackdump: a bool value to enable or disable stack dump in the fprobe handler.
