  Log:
  New SCSI target emulator code
  
  This code allows a user program to enable target mode on a SIM and
  then emulate any number of devices (disks, tape drives, etc.)  All
  decisions about device behavior (UA, CA, inquiry response) are left
  to the usermode program and the kernel driver is merely a conduit
  for CCBs.  This enables multiple concurrent target emulators, each
  using its own backing store and IO model.
  
  Also included is a user program that emulates a disk (RBC) using a
  file as a backing store.  This provides functionality similar to
  md(4) at the CAM layer.
  
  Code has been tested on ahc(4) and should also work on isp(4) (and
  other SIMs that gain target mode support).  It is a complete rewrite
  of /sys/cam/scsi_target* and /usr/share/examples/scsi_target.
