I thought one of the points was that building kernel with c++ catches some bugs, no? If the point is to make life easier for c++ userspace I'm not sure what we can do to be frank. C++ seems to be adding new keywords with no restraint (C99 did it with inline and restrict too, but it seems this stopped) so no good way to future-proof code for all language dialects.
So I'd like to know which are the actual c++ users asking for this - we can then accomodate the specific version they need. Meanwhile people can get by with a wrapper along the lines of #define class _class #include <linux/virtio_net.h> #undef class
