It used to be required to pass a enum km_type to kmap_atomic() and kunmap_atomic(), however this is no longer necessary and the wrappers zfs_k(un)map_atomic removed these. This is confusing in the ABD code as the struct abd_iter member iter_km no longer exists and the wrapper macros simply compile them out.
