Pages that are from the same folio do not necessarily need to be
consecutive. In that case, we cannot consolidate them into a single bvec
entry. Before applying the huge page optimization from commit 57bebf807e2a
("io_uring/rsrc: optimise registered huge pages"), check that the memory
is actually consecutive.
