 Samba tries to avoid "typedef struct { .. } x_t;", we always use
 "struct x { .. };". We know there are still those typedefs in the code,
 but for new code, please don't do that.

+Make use of helper variables
+----------------------------
+
+Please try to avoid passing function calls as function parameters
+in new code. This makes the code much easier to read and
+it's also easier to use the "step" command within gdb.
+
+Good Example::
+
+       char *name;
+
+       name = get_some_name();
+       if (name == NULL) {
+               ...
+       }
+
+       ret = some_function_my_name(name);
+       ...
+
+
+Bad Example::
+
+       ret = some_function_my_name(get_some_name());
+       ...
