No strong preference. Since this is very much not a bpf patch and
should be safe my intuition is to ship it to Linus ASAP and avoid 
any potential conflicts with other -next trees. Also riscv people 
may appreciate it getting fixed sooner rather than later. If they 
trip up the same dependency later on in the cycle and we've already
committed this patch to bpf-next they'd have to duplicate the patch
in their tree.
