Hi All,
I am using 4.9 kernel and I am observing NULL pointer deference type
kernel panic in the below scenario,
* Hotplug (i.e. hot add) the HBA (with a set of drives attached to it)
to the system just few seconds before issuing "poweroff" command.
* Observed that during drives discovery proces
To reduce the memory footprints of the driver in kdump kernel,
we have made below driver setting when system boots in to kdump kernel,
1. Used single MSI-x vector.
2. Disable RDPQ mode.
3. Set sg_table_size to 32 by default.
4) Set SCSI IO Queue depth to 200.

Updated the driver to remove the expander device from the list
only after freeing all its child devices.

Earlier driver is returning the IO with "DID_SOFT_ERROR"
that reties the IO quickly for five times but still
firmware needed some more time and hence IOs were failing.
