Bruce Evans dac6a0d559 Fix devstat on md devices. ... devstat_end_transaction() was called before the i/o was actually ended (by delivering it to GEOM), so at least the i/o length was messed up. It was always recorded as 0, so the average transaction size and the average transfer rate was always displayed as 0. devstat_end_transaction() was not called at all for the error case, so there were sometimes multiple starts per end. I didn't observe this in practice and don't know if it did much damage. I think it extended the length of the i/o to the next transaction. Reviewed by: kib		2018-12-09 15:34:20 +00:00
