HI Pingfan,
I haven't use kdump_pre and kdump_post much. Could you explain the use
cases of referring the storage or network device and also give some examples
of not adhering to 'Supported dump target types and requirements' in
kexec-kdump-howto.txt?

I think you should also change similar texts for kdump_pre.
