Cover letter [PATCH tip/core/rcu 0/3] Tiny RCU updates for 4.2
Hello!
This series contains updates to Tiny RCU, including a low-probability but quite real race condition.
1. Further shrink Tiny RCU by making empty functions static inlines.
2. Test both RCU-sched and RCU-bh for Tiny RCU, which located the
race condition fixed by #3 below.
3. Correctly handle non-empty Tiny RCU callback list with none ready.
Thanx, Paul
