unsigned int len,
unsigned int offset);

DESCRIPTION¶
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.COPYRIGHT¶
