SYNOPSIS

10                        unsigned int len, unsigned int offset);

ARGUMENTS

13       bio
14           destination bio
15
16       page
17           page to add
18
19       len
20           vec entry length

22       offset
23           vec entry offset

DESCRIPTION

26       Attempt to add a page to the bio_vec maplist. This can fail for a
27       number of reasons, such as the bio being full or target block device
28       limitations. The target block device must allow bio´s smaller than
29       PAGE_SIZE, so it is always possible to add a single page to an empty
30       bio.
