The removal of the batched object freeing has caused the debug_objects_freed
to become read-only, and the reading is inside an ifdef, so gcc warns that it
is completely unused without CONFIG_DEBUG_FS:
lib/debugobjects.c:71:14: error: 'debug_objects_freed' defined but not used [-Werror=unused-variable]
Assuming we are still interested in this number, this adds back code to
keep track of the freed objects.
Fixes: 636e1970fd7d ("debugobjects: Use global free list in free_object()")

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
