This looks good..

The comment on ipc_checkid() says that it should only be called with
the lock held.
Which seems entirely bogus, and I think it's just stale. It's just
checking the same ipc->seq that is only set at allocation, so it won't
change, afaik.
So I *think* the above is ok, but I'd want people to look at that
comment and remove it if it is stale. And if it's not stale, think
about this.
