-/**
- * list_for_each_off - iterate through a list of memory regions.
- * @h: the list_head
- * @i: the pointer to a memory region wich contains list node data.
- * @off: offset(relative to @i) at which list node data resides.
- *
- * This is a low-level wrapper to iterate @i over the entire list, used to
- * implement all oher, more high-level, for-each constructs. It's a for loop,
- * so you can break and continue as normal.
- *
- * WARNING! Being the low-level macro that it is, this wrapper doesn't know
- * nor care about the type of @i. The only assumption made is that @i points
- * to a chunk of memory that at some @offset, relative to @i, contains a
- * properly filled `struct list_node' which in turn contains pointers to
- * memory chunks and it's turtles all the way down. With all that in mind
- * remember that given the wrong pointer/offset couple this macro will
- * happily churn all you memory until SEGFAULT stops it, in other words
- * caveat emptor.
- *
- * It is worth mentioning that one of legitimate use-cases for that wrapper
- * is operation on opaque types with known offset for `struct list_node'
- * member(preferably 0), because it allows you not to disclose the type of
- * @i.
- *
- * Example:
- *	list_for_each_off(&parent->children, child,
- *				offsetof(struct child, list))
- *		printf("Name: %s\n", child->name);
