Thank you for good point.
makedumpfile does not fill it because makedumpfile might not be able to
get kernel debug information (containing symbol system_utsname/init_uts_ns).
makedumpfile does not need kernel debug information if dump_level is 0 or 1,
and it does not read a new_utsname structure. (check_release() is not called.)
The data structure does get read into a local new_utsname structure
in the
check_release() function, but it doesn't get saved and copied into the
disk_dump_header in write_kdump_header().
It would be helpful if that were in place as a quick ID for what the
compressed dumpfile contains.
I feel that is worth.
How about saving new_utsname data into disk_dump_header only if dump_level
is 2 or bigger ?
Thanks
