Use larger files and different writing styles to fill a 100MB filesystem to being full. In each case we should get very close to the filesystem being full before getting ENOSPC. This tests different types of ENOSPC failures to test 203 and requires more changes to pass. Signed-off-by: Dave Chinner <david@fromorbit.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
