Raw receiving a snapshot back to the originating dataset is currently impossible because of user accounting being present in the originating dataset. One solution would be resetting user accounting when raw receiving on the receiving dataset. However, to recalculate it we would have to dirty all dnodes, which may not be preferable on big datasets. Instead, we rely on the os_phys flag OBJSET_FLAG_USERACCOUNTING_COMPLETE to indicate that user accounting is incomplete when raw receiving. Thus, on the next mount of the receiving dataset the local mac protecting user accounting is zeroed out. The flag is then cleared when user accounting of the raw received snapshot is calculated.
