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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
