If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <lkp@intel.com>

Note: the linux-next/master HEAD 9dbf40840551df336c95ce2a3adbdd25ed53c0ef builds fine.
It may have been fixed somewhere.

This should be fixed by Arnd's commit in -rcu:
d22c97e39866 ("rcuscale: fix building with RCU_TINY")
Please let me know if this one does not do the trick.
Thanx, Paul
