This patch adds test case 023 which tests some more cluster sizes. For anythinger larger than 4k clusters we can't use requests that are l2_size or more (128k for 1k clusters, 2 MB for 4k clusters, 512 MB for 64k clusters). Therefore one of the common.pattern cases is changed and needs new expected results for some old test cases. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
