Currently there are two types of interfaces for listing datasets / snapshots / holds. ZFS_IOC_DATASET_LIST_NEXT / ZFS_IOC_SNAPSHOT_LIST_NEXT return strictly a single entity. ZFS_IOC_GET_HOLDS returns strictly all (or none, if they don't fit) holds .
It seems that the both approaches are not ideal from the points of view of the performance and the memory requirements. I think that a more balanced and universal approach could be to get entries via the iteration but with getting more than one entry per an iteration if the allocated memory allows that.
