We did all the original bidi testing on OSDs.  The OSD target
is now maintained by Boaz here:


It's not too difficult to set up.  OSDs need variable length
command blocks too.

The XDREADWRITE_10 command is also bidi.  This might be easier
to hack into the disk target if it is not already there.  See
the implementation in linux scsi_debug.c if it is helpful.
