Hi, While trying out a Linux 3.2 kernel I've noticed that the counters iodone_cnt and iorequest_cnt end up differing from each other after having written a file to disk with dd. Iorequest_cnt > iodone_cnt even a long time (several minutes) after the write is complete. The disk that was used for the file is an SSD connected via SATA. A friend has tested writing a file on his computer (running Debian wheezy with 3.1 kernel and on "rotating" disk connected via SATA) and sees the same behaviour. Actually the difference between the counters increases over time. When doing a file write on an HDD connected via SAS, I don't see this behaviour. Is this a known behavior for SATA?
