I always disliked the per chain spinlocks even for other hash tables like
TCP/UDP multiplex - it would be much nicer to use a much smaller separately
hashed lock table and save cache. In this case the special case of using
a one entry only lock hash table makes sense.
I agree, I do use a hashed spinlock array on my local tree for TCP, mainly to
reduce the hash table size by a 2 factor.
