It is not clear to me why this effort was started? As far as I know the 
null_blk driver is only used by kernel developers for testing kernel 
changes so end users are not affected by bugs in this driver. 
Additionally, performance of this driver is critical since this driver 
is used to measure block layer performance. Does this mean that C is a 
better choice than Rust for this driver?

Thanks,

Bart.
