Right now it is not possible to return a value larger than LONG_MAX on 32 bit systems. You can pass a rate of ULONG_MAX but can't return anything past LONG_MAX due to the fact both the rounded_rate and negative error codes are represented in the return value of round_rate().

Most implementations either return zero on error or don't return error codes at all. A minority of implementations do return a negative number - typically -EINVAL or -ENODEV.

At the higher level then callers of round_rate() typically and rightly check for a value of <= 0.

It is possible then to convert round_rate() to an unsigned long return value and change error code indication for the minority from -ERRORCODE to a simple 0.

This patch is the first step in making it possible to scale round_rate past LONG_MAX, later patches will change the previously mentioned minority of round_rate() implementations to return zero only on error if those implementations currently return a negative error number. Implementations that do not return an error code of < 0 will be left as-is.
