Cover letter [PATCH tip/core/rcu 0/6] Preview of RCU patches for 2.6.40
Hello!
This patchset introduces RCU_TREE priority boosting, a new "fire and forget" kfree_rcu() API, numerous uses of kfree_rcu(), plus a number of other fixes and improvements. The patches are as follows:
1. Remove conditional compilation for RCU CPU stall warnings, which
are now controlled only by the boot command line and sysfs.
2. Reworks RCU dyntick-idle interface to better tolerate theoretical
races introduced by expedited grace periods.
3-9. Introduce RCU priority boosting for TREE_RCU.
10-19. Upgrace TREE_RCU tracing to accommodate RCU priority boosting
and update documentation.
20-23. Make DEBUG_OBJECTS_RCU_HEAD work from !PREEMPT (thanks to
Mathieu Desnoyers).
24. Switch to this_cpu() primitives (thanks to Christoph Lameter).
25-27. Apply TREE_RCU priority-boosting lessons learned to TINY_RCU.
28. Avoid spurious diagnostics by moving from rcu_read_unlock() to
__rcu_read_unlock() in exit() patch (thanks to Lai Jiangshan).
29. Settle on "preemptible" spelling vs. "preemptable".
30. Introduce kfree_rcu() (thanks to Lai Jiangshan).
31. "Nice" down processes in rcu_yield(), which is called by RCU's
per-CPU kthreads to avoid monopolizing the CPU.
32. Improve latency by having call_rcu() avoid diving into the
RCU core code when called with irqs disabled.
33. Further reduce TINY_RCU's memory footprint (thanks to Eric
Dumazet).
34-70. Use kfree_rcu() throughout the kernel. This set of patches has
Acked-by's, so will go up -tip.
71-86. Ditto, but lacking Acked-by's.
