	sparse doesn't know __builtin_dynamic_object_size() and so the two size checks in the fdtable test fall apart on every config where the compiler has __counted_by_ptr: fs/tests/fdtable_kunit.c:25:9: sparse: undefined identifier '__builtin_dynamic_object_size' fs/tests/fdtable_kunit.c:25:9: sparse: incompatible types for operation (==): Use __struct_size() instead. Every compiler that has __counted_by_ptr also has __builtin_dynamic_object_size() so it expands to the same builtin and the test checks the same thing. sparse lacks the builtin and gets the __builtin_object_size() fallback which it does understand.

2026-09-10	vfs: Add KUnit tests for fdtable	Bill Wendling
	This adds a KUnit test suite for fdtable to verify correct allocation, max_fds initialization, and dynamic object size of the fd array under __counted_by_ptr when CONFIG_CC_HAS_COUNTED_BY_PTR is enabled.
