Name:Users of this function have their own bio allocation. Subsequently,* they must remember to pair any call to bio_init() with bio_uninit()* when IO has completed, or when the bio is released.
Proto:void bio_init(struct bio *bio, struct bio_vec *table, unsigned short max_vecs)
Type:void
Parameter:
