[PATCH 2/3] [XFSQA] Add simple delayed allocation ENOSPC test.

Subject: [PATCH 2/3] [XFSQA] Add simple delayed allocation ENOSPC test.

References: <1237114181-18431-1-git-send-email-david@xxxxxxxxxxxxx>
Using a small (100MB) filesystem and writing lots of
single block files can result in spurious ENOSPCs
being reported. Reproduce this test case so we can confirm
that it gets fixed.
