Currently one can set nice value to the process. But it only affects the
CPU scheduling, so if this process is CPU bound it would yield to others.
What if the process is disk-bound, like some backup operations? The
backup copying large disk seriously affects performance of all other
apps accessing the same disk.
Is there a way to set the priority value on the process for the disk
operations, so that all disk operations originating from the process
will be scheduled in similar way how CPU is scheduled based on the nice
value of the process? The disk-intense backup process with low disk
priority won't affect the other processes at all.
