Well, 15KLOC, and of course not including dependencies. But my point was that there will be a tiny, tiny amount of Rust in the kernel by comparison to the 10s of millions of lines of C code. Rust would have to compile radically slower than C, like hundreds or thousands of times slower, in order to be a limiting factor.
