- Fail if source block is smaller than destination. We can only grow blocks, not shrink them. - Fail if we do not have full znode range lock. In that case grow is not even called. We should improve zfs_rangelock_cb() somehow to know when cloning needs to grow the block size unlike write. - Fail of we tried to resize, but failed. There are many reasons for it to fail that we can not predict at this level, so be ready for them. Unlike write, that may proceed after growth failure, block cloning can't and must return error. This fixes assertion inside dmu_brt_clone() when it sees different number of blocks held in destination than it got block pointers. Builds without ZFS_DEBUG returned EXDEV, so are not affected much.
