The trace points were written to take a struct device input for the trace. In CXL multiple device objects are associated with each CXL hardware device. Using different device objects in the trace point can lead to confusion for users. The PCIe device is nice to have, but the user space tooling relies on the memory device naming. It is better to have those device names reported. Change all trace points to take struct cxl_memdev as a standard and report that name. Furthermore, standardize on the name 'memdev' in both /sys/kernel/tracing/trace and cxl-cli monitor output.

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.
