Mike McGowen 297bdc540f scsi: smartpqi: Close write read holes ... Insert a minimum 1 millisecond delay after writing to a register before reading from it. SIS and PQI registers that can be both written to and read from can return stale data if read from too soon after having been written to. There is no read/write ordering or hazard detection on the inbound path to the MSGU from the PCIe bus, therefore reads could pass writes.
