If so, i will respin and submit > the patches against the latest bpf-next This logic baffles me. I absolutely hate when people repost patches after I nack them without even as much as mentioning my objections in the cover letter. My concern was that we want the applications to encode fast path logic in BPF and load that into the kernel. So your patch works fundamentally against that goal: I worry that with the volume of patches that get posted each day objections of a measly contributor like myself will get forgotten if I don't reply to each posting, yet replying each time makes me look bullish or whatnot (apart from being an utter waste of time). Ugh.
