Great thanks.

You're not serious right? Especially the locking scheme is just
a extreme mess:
sometimes takes a lock, sometimes requires locking from the caller
even though the internal lock should be fine, sometimes uses unlocked
bitmap
operations outside a lock, all mixed with a partial RCU implementation,
no assumption is documented of course. etc.etc. It's a great poster child
for messy kernel code.
I read the code and I would be afraid touching it.
