Yes, I did build the entire kernel already and then I'm just trying to rebuild that module. In `include/linux/slab.h` if I remove the lines between `#ifdef CONFIG_TRACING` and `#else` (lines 473-480) and then the corresponding `#endif` and leave lines 481-499, I'm able to compile that module without issue.
