The SPDK null bdev driver is a dummy block I/O target that discards all writes and returns undefined
data for reads. It is useful for benchmarking the rest of the bdev I/O stack with minimal block
device overhead and for testing configurations that can't easily be created with the Malloc bdev.
To create Null bdev RPC command `construct_null_bdev` should be used.
To create Null bdev RPC command `bdev_null_create` should be used.
Example command
`rpc.py construct_null_bdev Null0 8589934592 4096`
`rpc.py bdev_null_create Null0 8589934592 4096`
This command will create an 8 petabyte `Null0` device with block size 4096.
To delete a null bdev use the delete_null_bdev command.
To delete a null bdev use the bdev_null_delete command.
`rpc.py delete_null_bdev Null0`
`rpc.py bdev_null_delete Null0`
