Will this work with older C++ compilers ?
No, this is a C++11 thing. I've added an extra check.
I think any sort of C++ support in Linux's exported headers would be a
big policy shift, and very unlikely in the foreseeable future, I'm
afraid.
Well, that would be sad. I know Linus has been vocal about using C++
within the kernel source, yet here we are talking about user-mode apps
consuming the kernel API.
The C header files just define the exported kernel data structures, the
ABI. It is safe for other languages to craft their own equivalent
definitions outside the kernel tree because the ABI, once exported,
should never change.
