Something like, I/O Sub-System; Storage Maintenance; Concurrency, etc.. There could be a section in the documentation with these topics as section headings and a listing and explanation of each of the possible code would then be described within. The meta-information is already embedded within the code/descriptions but explicitly pulling them out would be, IMO, more user-friendly and likely also aid in triage and speed-of-recognition when reading the corresponding code/description.
