Originally this test case was designed to work with 4K sectorsize. Now enhance it to work with any sector sizes and makes the following changes: .out file not to contain any traces of sector size. Use max_inline=0 mount option so that it meets the requisite of non inline regular extent. Don't log the md5sum results to the output file as the data size vary by the sectorsize.
