| |
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.
13. Shrink TINY_RCU a bit more by making reset_cpu_stall_ticks() and check_cpu_stalls() inlineable.
Changes from v1: Add Reviewed-bys and add the 13th patch.
Thanx, Paul
