2158 * For BIO_ZONE, this isn't normally needed. However, it

2160 * how much data was transferred.
2163 * XXX KDM we have a problem. But I'm not sure how to fix
2164 * it. devstat uses bio_bcount - bio_resid to calculate
2165 * the amount of data transferred. The GEOM disk code
2166 * uses bio_length - bio_resid to calculate the amount of
2167 * data in bio_completed. We have different structure
2168 * sizes above and below the ada(4) driver. So, if we
2169 * use the sizes above, the amount transferred won't be
2170 * quite accurate for devstat. If we use different sizes
2171 * for bio_bcount and bio_length (above and below
2172 * respectively), then the residual needs to match one or
2173 * the other. Everything is calculated after the bio
2174 * leaves the driver, so changing the values around isn't
2175 * really an option. For now, just set the count to the
2176 * passed in length. This means that the calculations
2177 * above (e.g. bio_completed) will be correct, but the
2178 * amount of data reported to devstat will be slightly
2179 * under or overstated.

3522 * a spindown. We send the former when we expect to lose power soon. For
3523 * a warm boot, we send the latter to avoid a thundering herd of spinups
3524 * just after the kernel loads while probing. We have to do something to
3525 * flush the data because the BIOS in many systems resets the HBA
3526 * causing a COMINIT/COMRESET negotiation, which some drives interpret
3527 * as license to toss the volatile data, and others count as unclean
3528 * shutdown when in the Active PM state in SMART attributes.

3531 * doesn't support it.
