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!
