Hi,<br> I have some conceptual questions about device driver :<br><br>1. Write order fidelity should be maintained when submitting requests from device driver to disk below.<br> However, acknowledging these requests it is okay if we don't necessarily maintain that order, right?<br>
<br>2. Also i want to understand what the device driver does say if in a multiple paged bio, some of the pages get written<br> and some don't, we send the error in the bio. But what about the pages it has already written??? It can't possibly<br>
do anything about it, right?<br><br><br>Regards,<br>Neha<br>
