Aha, seems makedumpfile will get the vmcoreinfo offset and size, then write the whole vmcoreinfo block into dumped vmcore header. But if specify '-g' for makedumpfile to only generate a vmcoreinfo file, it won't contain KERNEL_IMAGE_SIZE. makedumpfile -g vmcoreinfo -x vmlinux So I am not sure if you care about vmcoreinfo file, but you are right, I should not remove the vmcoreinfo reading and writing data. Thanks for pointing it out, will send v2 post. Thanks Baoquan
