2. Also i want to understand what the device driver does say if in a multiple paged bio, some of the pages get written and some don't, we send the error in the bio. But what about the pages it has already written??? It can't possibly do anything about it, right?
What do you mean by multiple paged bio? A bio, broken down into bio_vec is _always_ set of pages(or Am I missing something?), So, most of the time,you _will_ have a bio containing multiple pages. What about other field of bio structure; bi_idx, bi_size etc, Can we use those for partial completion? !!amit
