Thank you for the feedback.
I will improve these in the next patch.

> This does not support dumping with the crash --log  command, right?

Yes, that's right.
I think it's not possible to output the safe buffers with crash --log command
because symbols required to output the buffers are not included in vmcoreinfo
defined in log_buf_vmcoreinfo_setup().

Thanks,
