zil_claim_clone_range() takes references on cloned blocks before ZIL replay. Later zil_free_clone_range() drops them after replay or on dataset destroy. The total balance is neutral. It means we do not need to do anything (drop the references) for not implemented yet TX_CLONE_RANGE replay for ZVOLs. This is a logical follow up to openzfs#15603.

Is this change still forward compatible? @pjd |
|
@scineram Yes. The removed code is just not needed and was incorrectly removing reference that is already removed in other place. |
