Hi All,
These patches add more debugging options to scsi rdac device handler. This can considerably reduce the time taken to 
debug issues in big configurations and also very helpful in addressing the support issues.
Here is the summary of changes. 
- Added a bit mask "module parameter" rdac_logging with 2 bits for each type of logging.
- currently defined only two types of logging(failover and sense logging). Can be enhanced later if required.
- By default only failover logging is enabled which is equivalent of current logging.

Thanks to Chandra, Vijay and Bob for their useful comments. This code has been tested on 2.6.31-rc5.
