[vtk-developers] vtkAtomic vs std::atomic, can we change yet?

Are you asking about replacing just the
Core/SMP/Sequential/vtkAtomic.cxx implementation or are you also
interested in removing all the per SMP implementations?

Using http://en.cppreference.com/w/cpp/compiler_support we can see
that std::atomic is fully supported across the range of compilers we
need to support, so a conversion over to std::atomic would be allowed.
