There are a couple of places in the kublk selftests ublk server which use the legacy ublk opcodes. These operations fail (with -EOPNOTSUPP) on a kernel compiled without CONFIG_BLKDEV_UBLK_LEGACY_OPCODES set. We could easily require it to be set as a prerequisite for these selftests, but since new applications should not be using the legacy opcodes, use the ioctl-encoded opcodes everywhere in kublk.

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 reStructuredText 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.
