It can't go in until RCU is merged and that won't happen for 3.0.4 anyway.

When you post these again after 3.0.4 (which I'm sure you'll have to do) I'd
actually like the names as follows:
 1. Rename find_domain_by_id() to get_domain_by_id().
 2. Call the new function find_domain_by_id().

This has the obvious disadvantage of an old/new name clash so we effectively
change semantics of an existing function. *But* the new names are better
imo: get_domain_by_id() more obviously pairs with put_domain(), and
find_domain_by_id_noref() is ugly and this rename allows us to drop the
_noref suffix unambiguously.

I'd be interested to know what this does for find/get_domain_by_id()
percentages in your network profiles.
