Hi all,

After merging the kspp tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from ./usr/include/linux/posix_types.h:5,
                 from ./usr/include/linux/types.h:9,
                 from ./usr/include/rdma/rdma_user_rxe.h:37,
                 from <command-line>:32:
./usr/include/rdma/rdma_user_rxe.h:134:24: error: unknown type name 'u8'
  134 |   __DECLARE_FLEX_ARRAY(u8, inline_data);
      |                        ^~
./usr/include/linux/stddef.h:42:3: note: in definition of macro '__DECLARE_FLEX_ARRAY'
   42 |   TYPE NAME[]; \
      |   ^~~~

Caused by commit

  a908f2e5a6d0 ("treewide: Replace open-coded flex arrays in unions")

I have used the kspp tree from next-20210825 for today.
