I guess you mean what is currently bio_for_each_page_all in your
tree which now takes a bvec_iter_all agument? We could just
try to hide the bia variable initially under an unlike to be used
name, and then slowly move to the proper bio_for_each_page_all
API unhiding it with the rename.
But I think your current bio_for_each_segment_all should just
go away. All three users really should be using better abstractions.
