Bug ID: 26646
Summary: unexpectedly declaration-only types

being associated with the full DWARF definition, not the declaration.
I've sent in a patch which illustrates this bug (by changing the order in which
definitions and declarations are canonicalised). If need be, I can send over a
The patch serves as workaround for around 160 kernel types which appear
incomplete in the ABI.
