Add a benchmark to test the XOR functions for more representative block sizes and numbers of disks. Including 64k would be useful here, but increasing the test buffer size increases the runtime of the functional kunit test too much unfortunately. The runtime numbers are reported in GB/s as the numbers of modern implementations are basically unreadable as MB/s. This means retro-architectures could report 0, but that is an easy tradeoff.
