[Xen-devel] checking d->grant_table against NULL?

gnttab_prepare_for_transfer() is the only place in grant_table.c where
such a check happens. Is this check superfluous (and hence slightly
misleading), or are similar checks missing throughout the file? I suppose
the former, given that domains get inserted to the hash table only after
grant_table_create() ran, and get removed again before calling

Thanks, Jan
