[PATCH tip/core/rcu 0/12] TINY_RCU changes for 3.11

From: Paul E. McKenney
Date: Fri Apr 12 2013 - 19:48:26 EST


Hello!

This series removes TINY_PREEMPT_RCU, as promised/threatened at
http://lwn.net/Articles/541037/ and https://lkml.org/lkml/2012/11/12/545.

1. Remove TINY_PREEMPT_RCU. This is a straight syntactic removal,
with no attempt at cleanup. The remaining patches do the cleanup.

2. Inline the now-empty show_tiny_preempt_stats() function.

3. Inline the now-empty rcu_preempt_check_callbacks() function.

4. Inline the now-empty rcu_preempt_remove_callbacks() function.

5. Inline the now-empty rcu_preempt_process_callbacks() function.

6. Because TINY_RCU no longer has kthreads, remove the code that
used to abstract away kthread vs. softirq invocation.

7. Inline the now-empty check_cpu_stall_preempt() function.

8. Remove CONFIG_TINY_RCU ifdefs from include/linux/rcutiny.h

9. Inline the now-empty rcu_preempt_note_context_switch() function.

10. Move code to allow consolidating ifdefs in kernel/rcutiny_plugin.h.

11. Remove TINY_PREEMPT_RCU's tracing formats from documentation.

12. Shrink TINY_RCU a bit by moving exit_rcu() to TREE_RCU, leaving
TINY_RCU with a static inline empty function.

Thanx, Paul
