Note: this patch does not apply on top of current bpf-next [0] because __bpf_kfunc_start_defs and __bpf_kfunc are not present in [0].
[0] commit 58fd62e0aa50 ("bpf: Clarify batch lookup/lookup_and_delete semantics")
Right... this was in Linus' tree as a late 6.8-rcx addition. Depending on how bpf-next will be rebased/merged, I'll see if I merge this subseries through the HID tree or the BPF one.
Cheers, Benjamin
