Sebastien Boeuf 85bbf75fe8 block_util: Align buffers for O_DIRECT ... Whenever the backing file of our virtio-block device is opened with O_DIRECT, there's a requirement about the buffer address and size to be aligned to the sector size. We know virtio-block requests are sector aligned in terms of size, but we must still check if the buffer address is. In case it's not, we create an intermediate buffer that will be passed through the system call. In case of a write operation, the content of the non-aligned buffer must be copied beforehand, and in case of a read operation, the content of the aligned buffer must be copied to the non-aligned one after the operation has been completed.
