1) Why call flush_scheduled_work? This function will wait until
do_handling_work is finished. You could just call do_handling_work directly...

2) If you have heavy IO load, it might will up the workqueues. It should not
cause total starvation. But if (1) did not solve your problem, try reproducing
it while the system is idle.
