Hi, Arnd
Sorry to bother you again, please take the time to review the patch. Are there
any other suggestions?
Looking forward to your reply.

In Vmbus, we have defined a function to calculate available ring buffer
percentage to write.
Use that function and remove duplicate netvsc code.

This is a best effort for estimating on how busy the ring buffer is for
that channel, based on available buffer to write in percentage. It is still
possible that at the time of actual ring buffer write, the space may not be
available due to other processes may be writing at the time
From: Long Li
Netvsc has a similar function to calculate how much ring buffer in
percentage is available to write. This function is useful for storvsc and
other vmbus devices.
Define a similar function in vmbus to be used by storvsc.

Unlike SCSI and FC, we don't use multiple channels for IDE.
Also fix the calculation for sub-channels.

Hi,
I am running FIO script on Linux 4.15. This is generic behavior even on
3.x kernels as well. I wanted to know if my observation is correct or not.
Here is FIO command -
numactl -C 0-2 fio single --bs=4k --iodepth=64 --rw=randread
--ioscheduler=none --group_report --numjobs=2
