I think it reads better for io_uring and future extensions for io_uring
to contain the optimized bvec iter handler and setting the managed flag.
Too many disjointed assumptions the way the code is now. By pulling that
into io_uring, core code does not make assumptions that "managed" means
bvec and no page references - rather that is embedded in the code that
cares.
