ioprio: allow sys_ioprio_set() value of 0 to reset ioprio setting Normally io priorities follow the CPU nice, unless a specific scheduling class has been set. Once that is set, there's no way to reset the behaviour to 'none' so that it follows CPU nice again. Currently passing in 0 as the ioprio class/value will return -1/EINVAL, change that to allow resetting of a set scheduling class.
