[PATCH V1] smartpqi: raid bypass lba calculation fix

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: kevin Barnett <kevin.barnett@xxxxxxxxxxxxx>

In the ioaccel path, the calculation of the starting
LBA for READ(6)/WRITE(6) SCSI commands does not take
into account the most significant 5 bits of the
LBA: it only uses the least significant 16 bits of
the starting LBA.
