Allocation policy application programming interfaces
To make full use of multi-volume support features, VxFS supports allocation

allocations. A policy can be assigned to a file, file system, or Storage Checkpoint
created from a file system. When policies are assigned to objects in the file system,
you must specify how the policy maps to both metadata and file data. For example,
