Stefano Garzarella 37b06f8d46 virtio-blk: add DISCARD and WRITE_ZEROES features ... This patch adds the support of DISCARD and WRITE_ZEROES commands, that have been introduced in the virtio-blk protocol to have better performance when using SSD backend. We support only one segment per request since multiple segments are not widely used and there are no userspace APIs that allow applications to submit multiple segments in a single call.
