This document describes the SCSI subsystem as the Linux kernel enters the 2.4 production series. An external view of the SCSI subsystem is the main theme. Material is included to help the system administration of the Linux SCSI subsystem. There are also brief descriptions of ioctl()s and interfaces that may be relevant to those writing applications that use this subsystem.
