Would it be possible to have some global "kdump is configured + enabled" flag?

Then notifiers could make an informed choice on whether to deep dive to
get all the possible details (when there is no kdump) or just skim the high
level stuff (to maximize chance of getting a successful kdump).

Good idea Tony! What if I wire a kexec_crash_loaded() in the notifier?

I like this idea.

One small problem is that kexec_crash_loaded() has valid result
only under kexec_mutex. On the other hand, it should stay true
once loaded so that the small race window should be innocent.

With that, are you/Petr/Dinh OK in moving it for the info list?

Sounds good to me.
