With SET_PARTITION_INFO on the exclusive_cmds list for the CXL_PMEM driver, userspace cannot execute a set-partition command without first unbinding the pmem driver from the device. When userspace requests a partition change to take effect on the next reboot this unbind requirement is unnecessarily restrictive. The driver does not need to enforce an unbind because partitions will not change until the next reboot. Of course, userspace still needs to be aware that changing the size of persistent capacity on the next reboot will result in the loss of data stored. That can happen regardless of whether it is presently bound at the time of issuing the set-partition command. When userspace requests a partition change to take effect immediately, restrictions are needed. The CXL_MEM driver currently blocks the usage of immediate mode, making the presence of SET_PARTITION_INFO, in this exclusive commands list, redundant. In the future, when the CXL_MEM driver adds support for immediate changes to device partitions it will ensure that the partition change will not affect any active decode. That means the work will not fall right back here, onto the CXL_PMEM driver.

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.
