We're seeing the following new warnings on netdev/build_32bit and
netdev/build_allmodconfig_warn CI jobs:
../net/core/filter.c:8608:1: warning: symbol
'nf_conn_btf_access_lock' was not declared. Should it be static?
../net/core/filter.c:8611:5: warning: symbol 'nfct_bsa' was not
declared. Should it be static?
Fix by ensuring extern declaration is present while compiling filter.o.
Fixes: 864b656f82 ("bpf: Add support for writing to nf_conn:mark")

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.
