I need both bit_num(used inside function) and flag (1<<bit_num)
which is used by function caller.
No problem, i'll change it whenever you like
do you like following?
enum{
	IFN_BLKDEV_WAIT,	/* wait for completion */
	IFN_BLKDEV_BARRIER,	/*issue request with barrier */
};
#define BLKDEV_WAIT		(1 << IFN_BLKDEV_WAIT)
#define BLKDEV_BARRIER		(1 << IFN_BLKDEV_BARRIER)
