This one is already in -tip, so there is no time like the present to
notify my upstream maintainer, who I have added on CC.

Ingo, I agree with Stephen's analysis, so please feel free to revert
1a56f7d53b5c ("net/bridge: Replace call_rcu_bh() and rcu_barrier_bh()").
Or let me know if some other approach would be preferable.

I really did get an Acked-by, but perhaps my long development cycles for
RCU-related patches resulted in this being lost or forgotten.  Been
there myself...  ;-)
