Comment:
No, there is no `include/linux/compiler-gcc9.h` either, because (that's what I think) the version 9 does not need specific handling compared to previous compilers (5,6,7,8 I think). For gcc10 this is probably also not required, yet there is some test hidden somewhere which decides whether or not to expect a specific, versioned header, or whether to use the generic `compiler-gcc.h`.
