[lttng-dev] tracepoint sys_enter and sys_exit

[zhenyu.ren]

Hi,dev

  In lttng-modules-2.3.0/lttng-syscalls.c :

        ret = kabi_2635_tracepoint_probe_register("sys_enter",
                        (void *) syscall_entry_probe, chan);

       ret = kabi_2635_tracepoint_probe_register("sys_exit",
                        (void *) __event_probe__exit_syscall,

But where are these two tracepoints (hits) in kernel source code?

Thanks
