Hi Divya,

after discussions, we understood mention about O_DIRECT is not for any benefits of user, and it is very much a technical detail about the product, which it *should* handle. So, there is no need to elaborate on this option.

Hope this clarifies your doubts.

As per Amar's comment, this feature does not have documentation impact. Hence, closing this bug.
