<div>Dear all</div>
<div>I made a simple script that creates a 2MB file using directio write operation,</div>
<div>The objective was to test with different buffer sizes from 4K-5K-6K..8K, the buffer was filled with 5,</div>
<div>Than take hexdump of file to check data integrity.</div>
<div> </div>
<div>With 4K the file is fine, but with 5K, It can be noticed that </div>
<div> </div>
<div>there is zeroing is at 128K boundry further this shift 1K on successive 128K chunk.</div>
<div>I guess this is a bug. </div>
