xfstest: add fallocate/punch_hole vs AIO/DIO stress test
Run random AIO/DIO activity (fio's job:direct_aio_raicer) random fallocate activity(fio's job:falloc_raicer) and random punch_hole activity(punch_hole_raicer) on a common file in parallel. If a race exists, old dio request may rewrite punched block after it was allocated to another file, we will catch that by verifier fio's job: "aio-dio-verifier".

# AIO/DIO stress test

# Run random AIO/DIO activity and fallocate/punch_hole simultaneously
|

# Test will operate on huge sparsed file so ENOSPC is expected.
