[PATCH tip/core/rcu 0/2] Callback tagging for 3.9
Hello! This series contains callback-tagging patches. These were sent earlier in the idle/no-CBs series, but have been isolated as the more trustworthy part of that series. 1. Tag callback lists with the grace-period number that they are waiting for. This change enables a number of optimizations for RCU_FAST_NO_HZ, and though it add a bit of code, it greatly simplifies RCU's callback handling. 2. Trace callback acceleration (which is when RCU notices that a group of callbacks doesn't actually need to wait as long as it previously thought).
