The errno for "Numerical argument out of domain" is rarely seen in the kernel; it is primarily used by libaries in order to report that the program has attempted to use a value for a variable outside of the specified allowable range. In fact, this error is used almost exclsusively by libm. If this manner of error is reported by the kernel, it will be overwhelmingly likely that EINVAL will be the error return value of choice instead.
