[dm-devel] [PATCH] multipath_tools: add alias while printing checker_message

[Moger, Babu]

This patch adds alias while printing checker messages. 
Example of current Checker message. 

Apr 11 04:03:53 mymachine multipathd: sde: rdac checker reports path is down

Most of the time "sde" is meaningless when debugging the past failures. 

This patch add alias before the checker message..  
Example of the new message..
