Jeffle Xu 7d551b7d61 block: fix inflight statistics of part0 ... commit b0d97557eb upstream. The inflight of partition 0 doesn't include inflight IOs to all sub-partitions, since currently mq calculates inflight of specific partition by simply camparing the value of the partition pointer. Thus the following case is possible: $ cat /sys/block/vda/inflight        0        0 $ cat /sys/block/vda/vda1/inflight        0      128 While single queue device (on a previous version, e.g. v3.10) has no this issue: $cat /sys/block/sda/sda3/inflight 0 33 $cat /sys/block/sda/inflight 0 33 Partition 0 should be specially handled since it represents the whole disk. This issue is introduced since commit bf0ddaba65 ("blk-mq: fix sysfs inflight counter"). Besides, this patch can also fix the inflight statistics of part 0 in /proc/diskstats. Before this patch, the inflight statistics of part 0 doesn't include that of sub partitions. (I have marked the 'inflight' field with asterisk.) $cat /proc/diskstats 259 0 nvme0n1 45974469 0 367814768 6445794 1 0 1 0 *0* 111062 6445794 0 0 0 0 0 0 259 2 nvme0n1p1 45974058 0 367797952 6445727 0 0 0 0 *33* 111001 6445727 0 0 0 0 0 0 This is introduced since commit f299b7c7a9 ("blk-mq: provide internal in-flight variant").
