Please bear with me, I may be missing something obvious here.

Reassembly code returns a fragment_data to a dissector(say, tcp dissector
specifically). The dissector uses fragment_data->data in a call to
tvb_new_child_real_data(). fragment_data->data points to a buffer
containing the complete reassembled pdu. What will this data member contain
incase of a reassembly implementation which uses filebacked tvbuffs?
