Hello all, this patch series makes it possible to save a kernel crash dump when the kernel command line includes "crash_kexec_post_notifiers". There might be other approaches, but mine has the advantage that no new sysctl is required, and the behaviour is the same whether panic notifiers are run or not: If you load a crash kernel with kexec, it will be used, otherwise the hypervisor facility is used (using a hypercall). Feedback welcome!
