函数名称：syscall_enter_define_fields

函数原型：static int __init syscall_enter_define_fields(struct trace_event_call *call)

返回类型：int

参数：

类型参数名称
struct trace_event_call *call
276  meta等于data
279  offset等于offsetof(typeof(trace), args)
281  ret等于trace_define_field(call, SYSCALL_FIELD(int, nr, __syscall_nr), FILTER_OTHER)
283  如果ret则返回:ret
286  以i小于nb_args循环
287  ret等于trace_define_field(call, types[i], args[i], offset, sizeof(unsignedlong), 0, FILTER_OTHER)
291  offset加等于sizeof(unsignedlong)
294  返回:ret
