  22 # Description:
  23 # Verify incremental receive properly handles objects with changed
  24 # dnode slot count.
  25 #
  26 # Strategy:
  27 # 1. Populate a dataset with 1k byte dnodes and snapshot
  28 # 2. Remove objects, set dnodesize=legacy, and remount dataset so new objects
  29 #    get recycled numbers and formerly "interior" dnode slots get assigned
  30 #    to new objects
  31 # 3. Remove objects, set dnodesize=2k, and remount dataset so new objects
  32 #    overlap with recently recycled and formerly "normal" dnode slots get
  33 #    assigned to new objects
  34 # 4. Generate initial and incremental streams
  35 # 5. Verify initial and incremental streams can be received
  36 #
