- int bio_add_pc_page(struct request_queue * q, struct bio * bio, struct page * page, unsigned int len, unsigned int offset);
- the target queue
- destination bio
- page to add
- vec entry length
- vec entry offset
Attempt to add a page to the bio_vec maplist. This can fail for a number of reasons, such as the bio being full or target block device limitations. The target block device must allow bio's up to PAGE_SIZE, so it is always possible to add a single page to an empty bio.
This should only be used by REQ_PC bios.
