- * struct a {

- *
- * struct a {

- * beginning and end, respectively, of the bitfield (and things like
- * &x.flags_begin is allowed). As soon as the struct is allocated, the bit-
- * fields should be annotated:
- *
- * struct a *a = kmalloc(sizeof(struct a), GFP_KERNEL);
- * kmemcheck_annotate_bitfield(a, flags);
