Motivation is to allow to change bv_page field to include some context information and thus we need to go through an helper. This is done using a coccinelle patch and running it with (take ~30min): spatch --include-headers --sp-file spfile --in-place --dir . with spfile: %<--------------------------------------------------------------------- @exists@ struct bio_vec BVEC;
