how is this function different from the generic one? If not, why aren't
you using the generic one?
The intent is to allow remote management tools to trigger a clean
shutdown of the virtual machine. That requires us to notify to
userspace, and this function does that by exec'ing one of the standard
userspace programs. Given the trigger is received by the kernel in the
first instance I don't know a better way of doing this. And if this is
the best way, I don't think there is generic code in the kernel which
does the same thing.
