-// NOTE: despite the fact that this module is unstable,
-// stable Rust had the capability to access the stable
-// re-exported items from os::fd::raw through this
-// unstable module.
-// In PR #95956 the stability checker was changed to check
-// all path segments of an item rather than just the last,
-// which caused the aforementioned stable usage to regress
-// (see issue #99502).
-// As a result, the items in os::fd::raw were given the
-// rustc_allowed_through_unstable_modules attribute.
-// No regression tests were added to ensure this property,
-// as CI is not configured to test wasm32-wasi.
-// If this module is stabilized,
-// you may want to remove those attributes
-// (assuming no other unstable modules need them).
