I did a contrastive test by my colleagues Indoh's suggestion.

Btw, In the upstream kernel which contained this patch, I did two tests:
1) use the makedumpfile as core_collector in /etc/kdump.conf, then
trigger the process of kdump by echo 1 >/proc/sysrq-trigger, the
makedumpfile works well and I can get the vmcore file.
......It is OK
2) use cp as core_collector, do the same operation to get the vmcore
file. then use makedumpfile to do like above:
[douly@localhost code]$ ./makedumpfile -d 31 --message-level 31 -x
vmlinux_4.15+ vmcore_4.15+_from_cp_command vmcore_4.15+
......It causes makedumpfile failed.
Thanks,
dou.
