[PATCH 1/7] megaraid_sas : Jbod sequence number support

2015-08-07 Thread Sumit.Saxena
Implemented JBOD map which will provide quick access for JBOD path and also provide sequence number. This will help hardware to fail command to the FW in case of any sequence mismatch. Fast Path IO for JBOD will refer JBOD map (which has sequence number per JBOD devices) instead of Raid map.
