help
This driver supports HP Smart Array Controllers (circa 2009).
It is a SCSI alternative to the cciss driver, which is a block
driver. Anyone wishing to use HP Smart Array controllers who
would prefer the devices be presented to linux as SCSI devices,
rather than as generic block devices should say Y here.
