Hi "Björn,
I love your patch! Yet something to improve:

If you fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot <lkp@xxxxxxxxx>
All errors (new ones prefixed by >>):
s390-linux-ld: kernel/bpf/verifier.o: in function `fixup_bpf_calls':
verifier.c:(.text+0xa4fc): undefined reference to `get_xdp_redirect_func'
This is triggered when CONFIG_NET is not set. For some reason I thought
that BPF implied NET, but this was wrong. I'll fix this in v3.
