2205 * XXX KDM we have a problem. But I'm not sure how to fix
2206 * it. devstat uses bio_bcount - bio_resid to calculate
2207 * the amount of data transferred. The GEOM disk code
2208 * uses bio_length - bio_resid to calculate the amount of
2209 * data in bio_completed. We have different structure
2210 * sizes above and below the ada(4) driver. So, if we
2211 * use the sizes above, the amount transferred won't be
2212 * quite accurate for devstat. If we use different sizes
2213 * for bio_bcount and bio_length (above and below
2214 * respectively), then the residual needs to match one or
2215 * the other. Everything is calculated after the bio
2216 * leaves the driver, so changing the values around isn't
2217 * really an option. For now, just set the count to the
2218 * passed in length. This means that the calculations
2219 * above (e.g. bio_completed) will be correct, but the
2220 * amount of data reported to devstat will be slightly
2221 * under or overstated.
