Hi all,

After merging the bpf-next tree, today's linux-next build (x86_64
allnoconfig) failed like this:

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);
      |                                    ^~

Caused by commit

  b02e5a0ebb17 ("xsk: Propagate napi_id to XDP socket Rx path")

sk_buff only has a napi_id if defined(CONFIG_NET_RX_BUSY_POLL) ||
defined(CONFIG_XPS).

I have applied the following patch for today.
