Name

bio_advance — increment/complete a bio by some number of bytes

Synopsis

void bio_advance (struct bio * bio,
 unsigned bytes);
 

Arguments

struct bio * bio

bio to advance

unsigned bytes

number of bytes to complete

Description

This updates bi_sector, bi_size and bi_idx; if the number of bytes to complete doesn't align with a bvec boundary, then bv_len and bv_offset will be updated on the last bvec as well.

bio will then represent the remaining, uncompleted portion of the io.
