yes those work fine in kernel code, since variables to access
components of the structs/unions are allready availible for the
systemtap code and tapsets, but that is not the case of userland,
especially in the case of C++ classes/struct. So the user required to
enable guru-mode.
perhaps, you can enable guru-mode for including structs, but this of
course can polute the namespace.
