• Confirm that the removal of the bindings generation call does not break any build workflows; update documentation or build instructions accordingly if dependent processes exist.

crate::bindgen::generate_bindings();

build-scripts/kernel_build/src/cfiles/mod.rs:67

• Verify that removing the call to setup_common_files does not prevent necessary file inclusion for the build; if all C files are obsolete, ensure related directories are also cleaned up.

common::setup_common_files(&mut files);

我在想，gen_kallsyms要不独立成一个crate，放到build-scripts目录里面吧。这样的话其实方便管理（不会出现一个crate里面混着一个独立的rs文件这种情况）

还有就是，内核有些地方是extern “C”了 rs_xxxx的函数的，这些感觉也可以check一下是否可以删了。这些一般是当时为了导出给C用的。
