[dm-devel] [PATCH 0/3] scsi_dh_rdac: Adding more debug options for scsi rdac handler

["Moger, Babu" <Babu Moger lsi com>]

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 are 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 Seetharaman, Vijay Chauhan and Bob Stankey for their useful comments.
 This code has been tested on 2.6.27-rc5.

-Thanks
Babu Moger
