We use block_device_wait to wait for the zvol block device to actually appear, and we log the result of the dd calls by using an intermediate file.

# Description:
|
|
# Verify that compressed send correctly handles volumes
|
|
#
|
|
# Strategy:
|
|
# 1. Write compressible data into a volume, take a snap
|
|
# 2. Verify the compressed stream is the correct size, and has the correct data
|
|
# 3. Repeat step 2 for an incremental compressed stream
|
