25 # Verify encrypted raw incremental receives handle dnode reallocation.
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.
