  22 # Description:
  23 # Verify encrypted raw incremental receives handle dnode reallocation.
  24
  25 # Strategy:
  26 # 1. Create a pool containing an encrypted filesystem.
  27 # 2. Use 'zfs send -wp' to perform a raw send of the initial filesystem.
  28 # 3. Repeat the followings steps N times to verify raw incremental receives.
  29 #   a) Randomly change several key dataset properties.
  30 #   b) Modify the contents of the filesystem such that dnode reallocation
  31 #      is likely during the 'zfs receive', and receive_object() exercises
  32 #      as much of its functionality as possible.
  33 #   c) Create a new snapshot and generate an raw incremental stream.
  34 #   d) Receive the raw incremental stream and verify the received contents.
  35 #   e) Destroy the incremental stream and old snapshot.
