As a side-effect of adding the module option, we now get a section
mismatch warning:
WARNING: net/ipv4/netfilter/iptable_raw.o(.data+0x1c): Section mismatch in reference from the variable packet_raw to the function .init.text:iptable_raw_table_init()
The variable packet_raw references
the function __init iptable_raw_table_init()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
Apparently it's ok to link to a __net_init function from .rodata but not
from .data. We can address this by rearranging the logic so that the
structure is read-only again. Instead of writing to the .priority field
later, we have an extra copies of the structure with that flag. An added
advantage is that that we don't have writable function pointers with this
approach.

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.
