I'm a little confused about the reverse xmas tree ordering.
should I reorder them only according to the total length like this: void __iomem *ioaddr = (void __iomem *)dev->base_addr; int numhashregs = (hw->multicast_filter_bins >> 5); int mcbitslog2 = hw->mcast_bits_log2; unsigned int value; int i; or should I gather the same type together, and order types as reverse xmas tree, then order the same type definitions as reverse xmas tree, like this: void __iomem *ioaddr = (void __iomem *)dev->base_addr; unsigned int value; int numhashregs = (hw->multicast_filter_bins >> 5); int mcbitslog2 = hw->mcast_bits_log2; int i; Thank you. > > Thank you.
