# bio\_add\_pc\_page(9)

attempt to add page to bio

## NAME

bio\_add\_pc\_page - attempt to add page to bio

## SYNOPSIS

**int bio\_add\_pc\_page(struct request\_queue \*** *q***, struct bio \*** *bio***, struct page \*** *page***, unsigned int** *len***, unsigned int** *offset***);**

## ARGUMENTS

*q*

the target queue

*bio*

destination bio

*page*

page to add

*len*

vec entry length

*offset*

vec entry 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.
