Extend the SED block driver so it can alternatively obtain a key from a sed-opal kernel keyring. The SED ioctls will indicate the source of the key, either directly in the ioctl data or from the keyring. This allows the use of SED commands in scripts such as udev scripts so that drives may be automatically unlocked as they become available.

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.
