...ills down. OK, what I've found was; - The functions which can be ftraced look good. (see tracing/available_filter_functions) - following functions should not be able to be probed. - memcpy, memset - native_load_sp0 and some other native functions (need to be clear) - restore - trace_graph_return - trace_hardirqs_off_thunk, trace_hardirqs_on_thunk - This list still be not perfect. I just enabled/disabled kprobes one by one. There might be combined bugs (combination of several kprobes). - Some of them are hard to specify by NOKPROBE_SYMBOL because they are defined in asse...
