We normally like some patches (especially new functionality) to sit in linux-next for a while before the mering window (ideally starting with -rc4 or -rc5). We are at -rc6 already, so getting close to the 3.17 merging window. Another aspect is that the arm64/bpf branch depends on the net tree, so it can't easily go in via the arm64 tree for 3.17 (3.18 would not be a problem). -- Catalin -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
