Hmm; there's obsolete commands like usb_add and netdev_add as well. > With this sorted out, there is one special case left where the device > dynamically declares itself 'unmigratable' via migrate_add_blocker.

My preferred solution is to stop the device getting into the unmigratable state; so whatever function tries to set it should fail (nicely) and give an error - e.g the 9pfs should refuse to mount. I'm not sure how hard that is. Dave > Thanks > Ashijeet -- Dr. David Alan Gilbert / dgilb...@redhat.com / Manchester, UK
