Recently I went down a rabbit hole looking at a race condition in panic() on a Hyper-V guest. I assumed, since it was missing from the command line, that crash_kexec_post_notifiers was disabled. Only after a rather long reproduction and analysis process did I learn that Hyper-V actually enables this setting unconditionally. Users and debuggers alike would like to know when these things happen. I think it would be good to print a message to the kernel log when this happens, so that a grep for "crash_kexec_post_notifiers" shows relevant results.
