    [SCSI] target: Add LIO target core v4.0.0-rc6 · c66ac9db
    Nicholas Bellinger 提交于
    LIO target is a full featured in-kernel target framework with the
    following feature set:
    
    High-performance, non-blocking, multithreaded architecture with SIMD
    support.
    
    Advanced SCSI feature set:
    
        * Persistent Reservations (PRs)
        * Asymmetric Logical Unit Assignment (ALUA)
        * Protocol and intra-nexus multiplexing, load-balancing and failover (MC/S)
        * Full Error Recovery (ERL=0,1,2)
        * Active/active task migration and session continuation (ERL=2)
        * Thin LUN provisioning (UNMAP and WRITE_SAMExx)
    
    Multiprotocol target plugins
    
    Storage media independence:
    
        * Virtualization of all storage media; transparent mapping of IO to LUNs
        * No hard limits on number of LUNs per Target; maximum LUN size ~750 TB
        * Backstores: SATA, SAS, SCSI, BluRay, DVD, FLASH, USB, ramdisk, etc.
    
    Standards compliance:
    
        * Full compliance with IETF (RFC 3720)
        * Full implementation of SPC-4 PRs and ALUA
    
    Significant code cleanups done by Christoph Hellwig.
