The nf_tables.h header is used in a lot of files, but it turns out that there is only one actual user of nft_expr_clone(). Hence we relocate that function to be with the one consumer of it and avoid having to process it with CPP for all the other files. This will also enable a reduction in the other headers that the nf_tables.h itself has to include just to be stand-alone, hence a pending further significant reduction in the CPP content that needs to get processed for each netfilter file. Note that the explicit "inline" has been dropped as part of this relocation. In similar changes to this, I believe Dave has asked this be done, so we free up gcc to make the choice of whether to inline or not.

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.
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.
