* [BLOCK] cfq-iosched: fix slice_left calculationTejun Heo2005-11-121-2/+2
| | | | | | | | | | When cfq slice expires, remainder of slice is calculated and stored in cfqq->slice_left. Current code calculates the opposite of remainder - how many jiffies the cfqq has used past slice end. This patch fixes the bug.
