In commit cb1f69d53a ("sysfs: Add sysfs_emit and sysfs_emit_at to
format sysfs output") in 4.19.179, a #include <linux/mm.h> addition is
added to the fs/sysfs/file.c file, before sysfs.h is included in the
build. This ends up causing a previously "UNKNOWN" symbol type
definition of struct vm_operations_struct to become "known" which
propagates to a CRC change for some sysfs symbol definitions.
To prevent all this mess, add a simple #ifndef to prevent the mm.h file
from being included when running the symbol tool, and all is fine.

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.
