Sorry, I was thinking both short and long term.
Short term, it's probably easiest for the firewire stuff to access the
offline and removal functions from user land hotplug scripts (so they
don't actually need the in-kernel hook).
Long term we do need to see if we can go to a nice refcounted model for
all 50 odd list traversals. At least auditing them to see if we can use
a semaphore everywhere.
