So if we add a command to dump it from running kernel, it's not suitable. (This switch is intended to make a data that is used instead of vmlinux when vmcore didn't have VMCOREINFO and makedumpfile is in a situation that we don't have vmlinux. Please see the explanation of the -i and -g options in makefumpfile(8).) makedumpfile doesn't have any switch which dumps VMCOREINFO from kcore for now. (I'm thinking to have makedumpfile dump it as debug message, though.) Thanks, Kazu
