[Qemu-devel] [PATCH 5/7] block: default to 0 minimal / optiomal I/O size |

From: Christoph Hellwig <address@hidden>
Currently we set them to 512 bytes unless manually specified. Unforuntaly
some brain-dead partitioning tools create unaligned partitions if they
get low enough optiomal I/O size values, so don't report any at all
unless explicitly set.
