a bug in AS scheduler?

[Xiaoning Ding <dingxn@cse.ohio-state.edu>]

Hi,

I am reading the source code AS scheduler in 2.6.18(as-ioscheduler.c).
In function as_close_req, variable delay is in millisecond, while
ad->antic_expire is in jiffies. Doesn't the comparison of delay and
ad->antic_expire make any problem?
The related source code is quoted blow:

	if (ad->antic_status == ANTIC_OFF || !ad->ioc_finished)
		delay = 0;
	else
		delay = ((jiffies - ad->antic_start) * 1000) / HZ;

	if (delay == 0)
		delta = 8192;
	else if (delay <= 20 && delay <= ad->antic_expire)
		delta = 8192 << delay;
	else
		return 1;
