I made a kernel module in raspberry which dialog with external sensor to ask for temperature. to talk with the sensor, i should set gpio pins input and output for specified amount of time (in ms). and the module work fine. so are kernel modules not preempted by other processes by the scheduler, since if it's preempted, the timing will be wrong, and the result get from sensor will be wrong.
