The last fix was still wrong, as we need the inline dummy functions also for the case that CONFIG_HMM is enabled but CONFIG_HMM_MIRROR is not: kernel/fork.o: In function `__mmdrop': fork.c:(.text+0x14f6): undefined reference to `hmm_mm_destroy' This adds back the second copy of the dummy functions, hopefully this time in the right place.

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.
