3112 * XXX KDM we have a problem. But I'm not sure how to fix
3113 * it. devstat uses bio_bcount - bio_resid to calculate
3114 * the amount of data transferred. The GEOM disk code
3115 * uses bio_length - bio_resid to calculate the amount of
3116 * data in bio_completed. We have different structure
3117 * sizes above and below the ada(4) driver. So, if we
3118 * use the sizes above, the amount transferred won't be
3119 * quite accurate for devstat. If we use different sizes
3120 * for bio_bcount and bio_length (above and below
3121 * respectively), then the residual needs to match one or
3122 * the other. Everything is calculated after the bio
3123 * leaves the driver, so changing the values around isn't
3124 * really an option. For now, just set the count to the
3125 * passed in length. This means that the calculations
3126 * above (e.g. bio_completed) will be correct, but the
3127 * amount of data reported to devstat will be slightly
3128 * under or overstated.
