No, currently the hashtable only handles statically allocated hashtables. In this case, the downside is that you'll waste 8KB if hugepages aren't available, but the upside is that you'll have one less dereference when accessing the hashtable. If the 8KB saving is preferable here I'll drop the patch and come back when dynamic hashtable is supported.
