From bc8712f2b5250825968e6b0c3d2709a4b9d5d570 Mon Sep 17 00:00:00 2001 From: Amery Hung Date: Thu, 25 Sep 2025 10:00:12 -0700 Subject: [PATCH] bpf: Emit struct bpf_xdp_sock type in vmlinux BTF Similar to other BPF UAPI struct, force emit BTF of struct bpf_xdp_sock so that it is defined in vmlinux.h. In a later patch, a selftest will use vmlinux.h to get the definition of struct bpf_xdp_sock instead of bpf.h.
