    Description

      The linux kernel has its own resizable hashtable which can be used in place of libcfs hash code. The linux rhashtable was developed for the networking layer and that layer has very high requirements for performance. Some of the benefits are low latency as well as lockless lookups. Migrating Lustre to rhashtable should mean HUGE PERFORMANCE gains!!!!!
