> - Adds swab insns for 32/64-bit I don't like this. You don't want a swab instruction, you want "endian X to endian Y". Just like we have "cpu_to_le32()", "le32_to_cpu()" et al. in the kernel. That way the user can be completely oblivious as to the endianness of the cpu it's running on. So if you ask for a "to little endian" swab, if the chip is little-endian then no code needs to be emitted at all, it's a nop. There is zero reason for the BPF program emitted by userspace to be dependant upon the cpu endianness. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
