> When using Write Zeroes on a namespace that has protection information
> enabled they behavior without the PRACT bit counter-intuitive and will
> generally lead to validation failures when reading the written blocks.
> Fix this by always setting the PRACT bit that generates matching PI
> data on the fly.
