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