Well it seems that people are starting to want to hook the reboot
notifier, or the device shutdown facility in order to properly shutdown
pci drivers to make kexec work nicer.
So here's a patch for the PCI core that allows pci drivers to now just
add a "shutdown" notifier function that will be called when the system
is being shutdown. It happens just after the reboot notifier happens,
and it should happen in the proper device tree order, so everyone should
be happy.
Any objections to this patch?
Traditionally the proper place -has- been
* the reboot notifier
* the ->remove hook (hot unplug, and module remove)
which covers all the cases.
Add a ->shutdown hook is more of a hack. If you want to introduce this
facility in a systematic way, introduce a 'kexec reboot' option which
walks the device tree and shuts down hardware.
->shutdown is just a piecemeal, uncoordinated effort (uncoordinated in
the sense that driver shutdowns occur in an undefined order).
