Sigh. No. The comment header says it all:
/**
* roundup_pow_of_two - round the given value up to nearest power of two
* @n - parameter
*
* round the given value up to the nearest power of two
* - the result is undefined when n == 0
* - this can be used to initialise global variables from constant data
*/
Ie: round, say, 30 up to 32, not 5.
