Hi Dave,

Yup, that is expected. makedumpfile copies the vmcoreinfo into
compressed kdump file only if it is available in ELF vmcore. As of now
the s390x vmcore does not contain vmcoreinfo data and hence makedumpfile
does not populate it in compressed kdump file. In future when s390x
dumps starts including vmcoreinfo data, the makedumpfile will also
transfer it to compressed kdump file with it's existing logic.

Thanks,
-Mahesh.
