rds: Use RCU for the bind lookup searches

2010-09-09T01:15:08Z

The RDS bind lookups are somewhat expensive in terms of CPU time and locking overhead. This commit changes them into a faster RCU based hash tree instead of the rbtrees they were using before. On large NUMA systems it is a significant improvement. Signed-off-by: Chris Mason

rds: switch to rwlock on bind_lock

2010-09-09T01:12:26Z

The bind_lock is almost entirely readonly, but it gets hammered during normal operations and is a major bottleneck. This commit changes it to an rwlock, which takes it from 80% of the system time on a big numa machine down to much lower numbers. A better fix would involve RCU, which is done in a later commit Signed-off-by: Chris Mason

RDS: Add a debug message suggesting to load transport modules

2009-08-24T02:13:14Z

Now that RDS transports are no longer compiled-in to RDS core, there is now the possibility that they will not be loaded. This adds a helpful suggestion when rds_bind() fails to find a transport. Signed-off-by: Andy Grover Signed-off-by: David S. Miller
