Seeking clarification on this bug. Based on our earlier conversation, you had mentioned that this bug does not have any impact on docs. Kindly elaborate and clarify. Your clarification would help me resolve the bug.

Comment 5 Amar Tumballi 2013-02-18 09:40:24 EST
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.
