    bsg: deprecate BIDI support in bsg · 2e5b2d7c

    Besides the OSD command set that never got traction, the only SCSI
    command using bidirectional buffers is XDWRITEREAD in the 10 and 32 byte
    variants, which is extremely esoteric and has been removed from the spec
    again as of SBC4r15.  It probably doesn't make sense to keep the support
    code around just for that, so start deprecating the support.
