And for Jeff, CFI (Control Flow Integrity) is LLVM/clang supported runtime type check. If a pointer or function argument is different or incompatible with the declared type, a kernel warning or panic will be triggered depending on the configuration. https://clang.llvm.org/docs/ControlFlowIntegrity.html A CFI failure most likely means some runtime bugs.
