Re: [PATCH, RFC] RCU : OOM avoidance and lower latency

Andi Kleen a écrit :

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.
