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