Chris Mason	976673ee1b	rds: switch to rwlock on bind_lock ... 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 <chris.mason@oracle.com>	2010-09-08 18:12:26 -07:00

Andy Grover	f2c449320d	RDS: Add a debug message suggesting to load transport modules ... 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.
