Hi Matthew,
When creating this patch, I read and searched about the loff_t vs size_t. By mistake, I implemented it in the wrong way.
Also, I did not test it and just compiled it. I apologise for doing so.
And for the other points you have put as feedback. I will take some time to understand it. And would like to work on the changes you suggest.
Thanks & regards Sumitra
