Jan Engelhardt aca19e063b Do not attempt access beyond the declared end of the dn_blkptr array 
This loop in dmu_objset_write_ready():

	for (i = 0; i < dnp->dn_nblkptr; i++)
		bp->blk_fill += dnp->dn_blkptr[i].blk_fill;

invokes _undefined behavior_ for the (common) case of dn_nblkptr=3,
therefore, the compiler is free to do whatever it wants (such as
optimizing it away, or otherwise messing up your expections).

The fix is to be honest about the array size.
