Hi,

How much does this affect performance? If this affects performance
significantly I agree that this needs to be fixed.

We are testing megaraid-sas, with 24 jobs * 1024 iodepth, for randread
and randrw tests, v5.10 is about 20% better than v6.6.

I verified that just set wake_batch from 1 back to 8 can fix this.

Thanks,
Kuai
