QUESTION: 2.5 adds 1 to systats even for non I/O operations

I'm working in a daemon to control cpufreq and devices
(http://freshmeat.net/projects/cpudyn/)

I've just noticed that kernel 2.5 always add one (1) to /proc/diskstats and /sys/block/hdX/stat "reads" field for ioctl's requests that don't generate data I/O.

For example for checking the status of the disk (standby, active, sleep) or putting the disk in standby.

Is that correct? Do I have to take it in account always?

Thanks in advance.
