As explained in the commit message of 038ddf7: > https://doc.rust-lang.org/std/fmt/trait.LowerHex.html says "For primitive signed integers (i8 to i128, and isize), negative values are formatted as the two’s complement representation." >...

eBPF in Linux kernel just got extended to use the `0x06` class of instructions for 32-bit jumps. See [the merge commit](https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git/commit/?id=ae575c8a9868c2247c6ba287b91f0420e27aad4b) and its parents. This should land in kernel 5.1....
