Unfortunately, this doesn't build with v5.7 headers:
../types/check-io_uring.c:21:1: error: static assertion failed: "struct io_cqring_offsets size mismatch, please update the decoder or fix the kernel"
   21 | static_assert(sizeof(struct io_cqring_offsets) <= offsetof(struct_io_cqring_offsets, resv2),
      | ^~~~~~~~~~~~~

Apparently, types/gen.sh isn't friendly enough to field renames
in uapi headers.
