In some configurations, the sock_cgroup_ptr() function is not available:
net/netfilter/nft_socket.c: In function 'nft_sock_get_eval_cgroupv2':
net/netfilter/nft_socket.c:47:16: error: implicit declaration of function 'sock_cgroup_ptr'; did you mean 'obj_cgroup_put'? [-Werror=implicit-function-declaration]
47 | cgrp = sock_cgroup_ptr(&sk->sk_cgrp_data);
| ^~~~~~~~~~~~~~~
| obj_cgroup_put
net/netfilter/nft_socket.c:47:14: error: assignment to 'struct cgroup *' from 'int' makes pointer from integer without a cast [-Werror=int-conversion]
47 | cgrp = sock_cgroup_ptr(&sk->sk_cgrp_data);
| ^
Change the caller to match the same #ifdef check, only calling it
when the function is defined.

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.
