This test is based on generic/033, which originally used zero range operations to reproduce indlen reservation problems. Zero range now includes a pagecache flush before it updates extents, which means generic/033 is no longer able to reproduce the problem it was originally written to test. Create a new test that uses an XFS-specific mechanism (in DEBUG mode) to induce delalloc extent splits and reproduce the problem originally reproduced by generic/033. In addition, update the test to include a larger buffered write pattern that is known to reproduce premature indlen exhaustion on delalloc extents.
