- simplify the driver - there are a lot of quirky racy conditions not handled - causes more aborts/resets when the number of commands to be aborted is large, such as in multi-path fail-overs. - has been turned off in our internal driver since 8/31/2015 Reviewed-by:

- Block I/O requests with 0 length transfers which go down the ioaccel path. This causes lockup issues down in the basecode. - These issues have been fixed, but there are customers who are experiencing the issues when running older firmware. Reviewed-by:

create new worker thread to monitor controller events - both the rescan and event monitor workers can cause a rescan to occur however for multipath we have found that we need to respond faster than the normal scheduled rescan interval for path fail-overs. - getting controller events only involves reading a register, but the rescan worker can obtain an updated LUN list when there is a PTRAID device present. - move common code to a separate function. advantages: - detect controller events more frequently. - leave rescan thread interval at 30 seconds.

Now the driver issues a soft reset and waits for the controller to be up and running by periodically checking on the status of the controller health registers. Also prevents ARC adapters from issuing soft reset if IOP resets failed. Signed-off-by:
