Nit: I suggest "nvme/{032,040}" as the commit title prefix.

Nit: I checked fio man page, and did not find meaning of negative value for the
--runtime option. I also checked fio code, it looks that -1 is handled as
ULONG_MAX by type cast from singed long long to unsigned long long. Assuming
such negative values for the options are not well defined, --runtime=1d or
--runtime=365d would be the better to mean 'infinite runtime'.

Same as above.
