Stephen reported the following build error for !CONFIG_NET_RX_BUSY_POLL
built kernels:
In file included from fs/select.c:32:
include/net/busy_poll.h: In function 'sk_mark_napi_id_once':
include/net/busy_poll.h:150:36: error: 'const struct sk_buff' has no member named 'napi_id'
150 | __sk_mark_napi_id_once_xdp(sk, skb->napi_id);
| ^~
Fix it by wrapping a CONFIG_NET_RX_BUSY_POLL around the helpers.
Fixes: b02e5a0ebb ("xsk: Propagate napi_id to XDP socket Rx path")

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.
