Which Sphinx 3, :c:type: can't be used anymore for structs, as this should be used only for typedefs. Rely on automarkup.py for struct references. This file has an special case, though: it uses the tag also to point to an array. Let's use, instead, :c:expr: for such purpose, as it should do the right thing. This should fix this warning: ./Documentation/dev-tools/kgdb.rst:875: WARNING: Unparseable C cross-reference: 'kdb_poll_funcs[]' Invalid C declaration: Expected end of definition.
