Is there some lore about this I don't know?
”C++ is a horrible language. It's made more horrible by the fact that a lot of substandard programmers use it, to the point where it's much much easier to generate total and utter crap with it. Quite frankly, even if the choice of C were to do nothing but keep the C++ programmers out, that in itself would be a huge reason to use C.”

There is no C++ allowed in the Linux kernel and Linus has gone on several major rants about how terrible a language it is.
Is it all C?
There’s assembly and makefiles too
Less of a joke answer, there has been work to allow Rust bindings for drivers.
According to the github analysis, the kernel repository is:
So yeah, its basically all C, plus a tiny bit of assembly for very low level bootstrapping and some helper scripts.
Yeah but a lot of that C code has inline assembly so it's more like 5-10% asm.
Inline assembly is such a shit practice. But c++ bad.
Sometimes you can't get around it though.
Torvalds just really dislikes C++. He's gone on the record saying that he thinks it's just not a good language. In his own words "C++ is just a waste, there is no design at all, just adding some scum on top of C."
Never before have I been so offended by something I 100% agree with.
he's not wrong
In the specific use case of kernel programming, maybe. But the Standard Template Library is awesome.
they dumped everything in the languaga, at least samething they needed to have right, it's otherwise statistically impossible
