Hello Anil Ravindranath,
The patch 89a368104150: [SCSI] pmcraid: PMC-Sierra MaxRAID driver to
support 6Gb/s SAS RAID controller from Aug 25, 2009, leads to the
following static checker warning:
This patch set implements the PMP support for APM X-Gene SoC AHCI SATA Host
Controller driver.

Suman Tripathi (2):
ahci_xgene: Implement the xgene_ahci_poll_reg_val to support PMP.
ahci_xgene: Implement the workaround to support PMP
Due to H/W errata, the controller is unable to save the PMP
field fetched from command header before sending the H2D FIS.
When the device returns the PMP port field in the D2H FIS, there is
a mismatch and results in command completion failure. The workaround
is to write the pmp value to PxFBS.DEV
This patch implements the function xgene_ahci_poll_reg_val
to poll PxCI for multiple IDENTIFY DEVICE commands to finish before
restarting the DMA engine.

There is a race condition in virtscsi_handle_event, when many device
hotplug/unplug events flush in quickly.
The scsi_remove_device in virtscsi_handle_transport_reset may trigger
the BUG_ON in scsi_target_reap, because the state is altered behind it,
probably by scsi_scan_host of another event.
For any SCSI command, if the driver receives IOC status = SCSI_IOC_TERMINATED
and log info = 0x32010081
then that command will be completed with DID_RESET host status.
The definition of this log info value is Virtual IO has failed and has to be
retried.
Firmware will provide this log info

This patch avoids the arbitrary limiting of I/O size to fabric_max_sectors,
which currently has a hardcoded max of 8192 (4 MB for 512 byte sector

This is problematic because Linux initiators have only recently started
