Current implementation exports only to /sys/bus/cxl/devices/.../memN/qos_class. With both ram and pmem exposed, the second registered sysfs attribute is rejected as duplicate. It's not possible to create qos_class under the dev_groups via the driver due to the ram and pmem sysfs sub-directories already created by the device sysfs groups. Move the ram and pmem qos_class to the device sysfs groups and add a call to sysfs_update() after the perf data are validated so the qos_class can be visible. The end results should be /sys/bus/cxl/devices/.../memN/ram/qos_class and /sys/bus/cxl/devices/.../memN/pmem/qos_class.

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.
