- * Despite constifying struct kernel_param_ops, some older kernels define a
- * `__check_old_set_param()` function in their headers that checks for a
- * non-constified `->set()`. This has long been fixed in Linux mainline, but
- * since we support older kernels, we workaround it by using a preprocessor
- * definition to disable it.
