There's no need to retain the fs/autofs4 directory for backward compatibility. Adding an AUTOFS4_FS fragment to the autofs Kconfig and a module alias for autofs4 is sufficient for almost all cases. Not keeping fs/autofs4 remnants will prevent "insmod <path>/autofs4/autofs4.ko" from working but this shouldn't be used in automation scripts rather than modprobe(8). There were some comments about things to look out for with the module rename in the fs/autofs4/Kconfig that is removed by this patch, see the commit patch if you are interested. One potential problem with this change is that when the fs/autofs/Kconfig fragment for AUTOFS4_FS is removed any AUTOFS4_FS entries will be removed from the kernel config, resulting in no autofs file system being built if there is no AUTOFS_FS entry also. This would have also happened if the fs/autofs4 remnants had remained and is most likely to be a problem with automated builds. Please check your build configurations before the removal which will occur after the next couple of kernel releases.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
