However, I'm not clear about how much of the problem I'm addressing will be solved by using a kdump hook. If I understand correctly, you'd still need a pseudo-file somewhere to actually get the data from user space to kernel space. *Then* you could use a kdump hook to transfer the data to flash or some memory area that will be retained across boots. Is this the approach to which you were referring? If so, I have a couple more questions: 1. In what ways would this be better than, say, a panic_notifier? 2. Where would you suggest tying in?
