Add -h switch to zfs send command to send dataset holds. If holds are present in the stream, zfs receive will create them on the target dataset, unless the zfs receive -h option is used to skip receive of holds.

# DESCRIPTION:
|
|
# Verify 'zfs send' can send dataset holds.
|
|
# Verify 'zfs receive' can receive dataset holds.
|
|
#
|
|
# STRATEGY:
|
|
# 1. Create a snapshot.
|
|
# 2. Create a full send stream with the fs, including holds.
|
|
# 3. Receive the send stream and verify the data integrity.
|
|
# 4. Fill in fs with some new data.
|
|
# 5. Create an incremental send stream with the fs, including holds.
|
|
# 6. Receive the incremental send stream and verify the data integrity.
|
|
# 7. Verify the holds have been received as expected.
|
|
# 8. Create an incremental snap with no holds, and send that with -h.
|
|
# 9. Confirm the snapshot was received as expected.
|
|
# 10. Create an incremental snapshot and place a hold on it.
|
|
# 11. Receive the incremental stream with -h and verify holds skipped.
