CXL PMEM security operations are routed through the NVDIMM sysfs interface. For this reason the corresponding commands are marked "exclusive" to preclude collisions between the ioctl ABI and the sysfs ABI. However, a better way to preclude that collision is to simply remove the ioctl ABI (command-id definitions) for those operations. Now that cxl_internal_send_cmd() (formerly cxl_mbox_send_cmd()) no longer needs to talk the cxl_mem_commands array, all of the uapi definitions for the security commands can be dropped. These never appeared in a released kernel, so no regression risk.

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.
