This patch adjusts the file size so this assumption is always true. As an example, here's test06 output for cephfs, where the allocation size is set to 4194304, and the output is (4194304 * 10 + 4194304) 07. Test file with unwritten extents, only have dirty pages 07.01 SEEK_HOLE expected 0 or 4194304, got 46137344. FAIL 07.02 SEEK_HOLE expected 1 or 4194304, got 46137344. FAIL (Note: The test will be skipped if an integer overflow occurs.)
