Currently in btrfs, there is something wrong with fallocate(2)'s data space reservation, it'll temporarily occupy more data space thant it really needs, which in turn will impact other operations' data request. In this test case, it runs write(2) and fallocate(2) in parallel and the total needed data space for these two operations don't exceed whole fs free data space, to see whether we will get any unexpected ENOSPC error.
