Hello!
This patch contains fixes as follows:
1. Reinstate a grace-period acceleration that permits invoking
the first callback registered on an idle system in one grace
period rather than two. The previous version of this acceleration
was invalidated by the new grace-period kthreads.
2. Fix an integer-size mismatch that prevented RCU from shifting
to bulk-callback-invocation mode under overload. (Courtesy of
Eric Dumazet.)
3. Remove list_for_each_continue_rcu(), as it is no longer used.
4. Update rcutorture's module-parameter printout to include new
parameters.
5. Document the memory-ordering properties of RCU's grace-period
primitives. Note that the SRCU rewrite weakened these properties
slightly.
6. Reduce the RCU CPU stall warning timeout to 21 seconds so that
it is once again somewhat shorter than the soft-lockup timeout.
Thanx, Paul
