Hello,
Using 4.2-rc8 kernel, I can confirm that merges are happening aft
Hi Rafal,
Please have a try adding "--iodepth_batch=32 --iodepth_batch_complete=32" to
the fio command line.
I didn't see this issue any more, neither for domU.
Thanks,
-Bob

Hi Jens & Christoph,
Rafal reported an issue about this patch, that's after this patch no more
merges happen and the performance dropped if "modprobe null_blk irqmode=2
completion_nsec=100",
but works fine if "modprobe null_blk".
I'm not sure whether it's as expect or not.
Do you have any
