Similar concern here; we'll have to traverse the entire tree here.
But if that's of no concern...
Hi Hannes,
If I measure IOPS for a null_blk device instance then I see the
following performance results for a single CPU core:
* No I/O scheduler: 690 K IOPS.
* mq-deadline, without this patch series: 147 K IOPS.
* mq-deadline, with this patch series: 146 K IOPS.
In other words, the performance impact of this patch series on the
mq-deadline scheduler is small.
Thanks,
Bart.
