+    [hurd] Fix accessing f_type field of statvfs (#71851)
+    
+    f4719c4d2cda ("Add support for GNU Hurd in Path.inc and other places")
+    made llvm use an internal __f_type name for the f_type field (which it
+    is not supposed to since accessing double-underscore names is explicitly
+    not supported by standards). In glibc 2.39 this field was renamed to
+    f_type so application can now access the field as the standard says.
