Application Interface

To keep the system flexible and the implementation simple, we have tried to offload the policy decisions to user level applications4. The driver provides interfaces using which an application (necessarily with root privileges) can access the driver data such as logical to physical translation table, stripe access information, physical stripe allocation bitmap and services such as initiating migrations, punching holes, etc.
