This can be used to trigger an assert in the current XFS code because it can't handle the case where there are COW extents on a file, but none at or below the range converted by the AIO completion handler. Note that it doesn't trigger the assert 100% but fairly reliably. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.
