Please either add the actual flags here, or if there is a good reason to
do that later add the meta_flags_t type and the member when adding
it.  Also maybe the type name wants a prefix, maybe uio?

Also from looking at the reset of the series uio_meta is in no way
block specific and referenced from io_uring.  So this probably should
go into uio.h?
