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.
