Most drivers don't have shutdown() methods, but they do have remove() methods that clean everything up. Those methods tend to vanish from statically linked kernels. Seems that if kexec were to use remove() methods that'd probably resolve a lot of those issues. I confess I still don't see much point to a shutdown() method, unless maybe it's to avoid using reboot notifiers for that subset of remove() logic. - Dave ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
