Anonymous structs/unions. I used to have a use case for that in struct efi_dev_path in include/linux/efi.h, but Ard Biesheuvel refactored it in a gnu89-compatible way for v5.7 with db8952e7094f. [The above was copy-pasted from last time this discussion came up in July 2020. Back then, Kirill Shutemov likewise mentioned the local variables in loops feature: https://lore.kernel.org/lkml/[email protected]/ ] Thanks, Lukas
