  3. Module Name:
  4. fsp_dir.c
  5. Abstract:
  6. This module contains the entry points for the AFP directory APIs. The API
  7. dispatcher calls these. These are all callable from FSD. All of the APIs
  8. complete in the DPC context. The ones which are completed in the FSP are
  9. directly queued to the workers in fsp_dir.c
