We have already worked on wait_event usage in megasas_issue_blocked_cmd.
That code will be posted by LSI once we received test result from

If you see the current OCR code in Linux Driver we do re-send the IOCTL

Hannes,
This patch really not required, since MR controller can still operate even if
ld map info is failed.
We just disable Fast Path IO if LD map info is failed, so we can still continue
without ld map.
This patch is not required for megaraid_sas driver.

the use of many functions in this path in addition to the normal
