cfq-iosched: Convert slice_resid from u64 to s64 slice_resid can be both positive and negative. Commit 9a7f38c42c2b (cfq-iosched: Convert from jiffies to nanoseconds) converted it from long to u64. Although this did not introduce any functional regression (the operations just overflow and the result was fine), it is certainly wrong and could cause issues in future. So convert the type to more appropriate s64. Fixes: 9a7f38c42c2b92391d9dabaf9f51df7cfe5608e4 Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Jens Axboe <axboe@fb.com>
