  "message": "qapi: Avoid use of misnamed DO_UPCAST()\n\nThe macro DO_UPCAST() is incorrectly named: it converts from a\nparent class to a derived class (which is a downcast).  Better,\nand more consistent with some of the other qapi visitors, is\nto use the container_of() macro through a to_FOO() helper.  Names\nlike \u0027to_ov()\u0027 may be a bit short, but for a static helper it\ndoesn\u0027t hurt too much, and matches existing practice in files\nlike qmp-input-visitor.c.\n\nOur current definition of container_of() is weaker than\nDO_UPCAST(), in that it does not require the derived class to\nhave Visitor as its first member, but this does not hurt our\nusage patterns in qapi visitors.\n\nSigned-off-by: Eric Blake \u003ceblake@redhat.com\u003e\nReviewed-by: Marc-André Lureau \u003cmarcandre.lureau@redhat.com\u003e\nMessage-Id: \u003c1454075341-13658-3-git-send-email-eblake@redhat.com\u003e\nSigned-off-by: Markus Armbruster \u003carmbru@redhat.com\u003e\n",
