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;
