This feature gives the user RW access to any opal table with admin1 authority. The flags described in the new structure determines if the user wants to read/write the data. Flags are checked for valid values in order to allow future features to be added to the ioctl. The user can provide the desired table's UID. Also, the ioctl provides a size and offset field and internally will loop data accesses to return the full data block. Read overrun is prevented by the initiator's sec_send_recv() backend. The ioctl provides a private field with the intention to accommodate any future expansions to the ioctl.

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.
