With removal of libcfs/heap.c, it's header can also go away now.

-/** \defgroup heap Binary heap
- *
- * The binary heap is a scalable data structure created using a binary tree. It
- * is capable of maintaining large sets of elements sorted usually by one or
- * more element properties, but really based on anything that can be used as a
- * binary predicate in order to determine the relevant ordering of any two nodes
- * that belong to the set. There is no search operation, rather the intention is
- * for the element of the lowest priority which will always be at the root of
- * the tree (as this is an implementation of a min-heap) to be removed by users
- * for consumption.
- *
- * Users of the heap should embed a \e cfs_binheap_node_t object instance on
- * every object of the set that they wish the binary heap instance to handle,
- * and (at a minimum) provide a cfs_binheap_ops_t::hop_compare() implementation
- * which is used by the heap as the binary predicate during its internal sorting
- * operations.
- *
- * The current implementation enforces no locking scheme, and so assumes the
- * user caters for locking between calls to insert, delete and lookup
- * operations. Since the only consumer for the data structure at this point
- * are NRS policies, and these operate on a per-CPT basis, binary heap instances
- * are tied to a specific CPT.
