2178 * For BIO_ZONE, this isn't normally needed. However, it

2183 * XXX KDM we have a problem. But I'm not sure how to fix
2184 * it. devstat uses bio_bcount - bio_resid to calculate
2185 * the amount of data transferred. The GEOM disk code
2186 * uses bio_length - bio_resid to calculate the amount of
2187 * data in bio_completed. We have different structure
2188 * sizes above and below the ada(4) driver. So, if we
2189 * use the sizes above, the amount transferred won't be
2190 * quite accurate for devstat. If we use different sizes
2191 * for bio_bcount and bio_length (above and below
2192 * respectively), then the residual needs to match one or
2193 * the other. Everything is calculated after the bio
2194 * leaves the driver, so changing the values around isn't
2195 * really an option. For now, just set the count to the
2196 * passed in length. This means that the calculations
2197 * above (e.g. bio_completed) will be correct, but the
2198 * amount of data reported to devstat will be slightly
2199 * under or overstated.
