-/**
- * @file
- * Simple memory pool for equally sized memory allocations.
- * util_mempool_malloc and util_mempool_free are in O(1).
- *
- * Good for allocations which have very low lifetime and are allocated
- * and freed very often. Use a profiler first!
- *
- * Candidates: get_transfer, user_buffer_create
- *
