This patch contains the SCST virtual disk backend device handler. This is an SCST device handler that allows to export local files or local block devices as SCSI devices through the SCST target framework. This handler has three modes: - FILEIO mode, which allows to use files on file systems or block devices as virtual remotely available SCSI disks or CDROMs with benefits of the Linux page cache. - BLOCKIO mode, which performs direct block IO with a block device, bypassing page-cache for all operations. This mode works ideally with high-end storage HBAs and for applications that either do not need caching between application and disk or need the large block throughput. - NULLIO mode, in which no real IO is performed. It is intended for performance testing.
