SCSI Enclosure Services (SES) permit "the management and sense the state of power supplies, cooling devices, displays, indicators, individual drives, and other non-SCSI elements installed in an enclosure". The scsi_ses adapter driver simulates a SES device. The default action is to appear as a disk (actually an 8 MB ramdisk) with associated Enclosure Services. This is similar to a fibre channel disk with a SCA-2 connector which includes an Enclosure Services Interface (ESI). Alternatively the scsi_ses driver can simulate a simple SES device.
This SES simulator is closely related to the scsi_debug driver. Unlike scsi_debug which can simulate many disks (or other scsi device types), scsi_ses simulates a single disk with an attached SES device. Alternatively it can simulate a freestanding SES device when the "ses_only=1" parameter is given.

RFC: Does this driver warrant inclusion in the lk 2.6 series?
The current scsi_ses patches do not take into account Mike Christie's "scsi bus for virtual drivers" changes. These can be easily applied and will bring the same advantages as they do to the existing scsi_debug and iSCSI drivers.
