With the upcoming restructuring having all in a single file simplifies things a bit. The relevant and somewhat visible changes are: - Some dropped prototypes from include/linux/pwm.h that were only necessary that core.c has a declaration of the symbols defined in sysfs.c. The respective functions are static now. - The pwm class now also exists if CONFIG_SYSFS isn't enabled. Having CONFIG_SYSFS is not very relevant today, but even without it the class and device stuff still provides lifetime tracking. - Both files had an initcall, these are merged into a single one now. Instead of a big #ifdef block for CONFIG_DEBUG_FS, a single if (IS_ENABLED(CONFIG_DEBUG_FS)) is used now. This increases compile coverage a bit and is a tad nicer on the eyes.

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 reStructuredText 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.
