I read parts of the Linux kernel source code pretty often, and getting the definition of a function is often pretty involved: - I don't always know the return code type, as the calling code assigned a field whose definition I don't know to find either - I don't know if it's a C function or a preprocessor macro This often results in me searching for the exact function name, and combing through the uses in the drivers. You then need to re-start all that recursively to understand the function you just read. I could use clangd for that, but I don't have the ressources on my laptop to compile a kernel
