Hello,
   I have few questions regarding dm-delay component.
1. Why type of emulations is targeted while implementation of dm-delay?
 2. Is the delay uniform across different i/o going to the device?
 3. Can the granularity of be reduced from mili-sec to tens of micro-sec?
If so how?

My aim is to emulate ssd devices latency varying from 10us to 100ms on
ramdisk using dm-delay.

Regards,
Sourav
