Some lints are emitted from a from a different from the area they are linted. e.g. clippy::ptr_arg is linting from check_body, but it can be allowed from the argument (fn foo(#[allow(clippy::ptr_arg)] x: &Vec<u32>) {}).
The following lints in clippy (and probably more) lint from different check_* functions:
needless_borrowref_binding_to_refduplicate_modmultiple_inherent_implmacro_use_importsmanual_non_exhaustivesame_name_methodasync_yields_asyncawait_holding_lockawait_holding_refcellawait_holding_invalid_typedefault_numeric_fallbackptr_argredundant_clonelogic_bugnonminimal_boolboxed_localimplicit_returnneedless_returnunnecessary_unwrappanicking_unwrap
Some of these don't actually work with allow at a narrower scope either, but some of them check to see if the lint has been allowed on the target item before emitting the lint.
