70  *   Here it is trace_foo_bar(char *foo, int bar).
73  *    Here it is simply "foo, bar".
85  *        __field(int, foo)
87  *        __entry->foo = 5;
94  *         __field_struct(struct bar, foo)
102  *         __array( char, foo, 10) is the same as saying: char foo[10];
106  *         __entry->foo[0] = 'a';
108  *         memcpy(__entry->foo, bar, 10);
119  *         __dynamic_array( int, foo, bar) is similar to: int foo[bar];
124  *         memcpy(__get_dynamic_array(foo), bar, 10);
135  *         __string(foo, bar)  is similar to:  strcpy(foo, bar)
139  *         __assign_str(foo, bar);
154  *         __vstring(foo, fmt, va)  is similar to:  vsnprintf(foo, fmt, va)
158  *         __assign_vstr(foo, fmt, va);
175  *         __string_len(foo, bar, len)
179  *         __assign_str_len(foo, bar, len);
184  *         memcpy(__get_str(foo), bar, len);
185  *         __get_str(foo)[len] = 0;
189  *        for the '\0' terminating byte, and __get_str(foo) can be used
228  *      For __dynamic_array(int, foo, bar) use __get_dynamic_array(foo)
229  *            Use __get_dynamic_array_len(foo) to get the length of the array
235  *      For __string(foo, bar) use __get_str(foo)
