- When reading L0 block pointers handle buffers without ones and without dirty records as a holes. Those appear when dnode size was increased, but the end was never written, so there are no new indirection levels to store the pointers. It makes no sense to return EAGAIN here, since sync won't create new indirection levels until there will be actual writes. - When cloning blocks set destination hole logical birth time to the current TXG. Otherwise if we are cloning over existing data, newly created holes may not be properly replicated later. Use BP_SET_BIRTH() when possible to not replicate its logic.
