Hello, Ingo,
This pull request covers RCU changes for 2.6.38. These include RCU
priority boosting for TINY_RCU and TINY_PREEMPT_RCU, some cleanups from
Lai Jiangshan, fixes to synchronize_sched_expedited() including some
from Tejun Heo, some nohz fixes from Frederic Weisbecker, some changes
to reduce lock contention for internal-to-RCU locks, and a fix from
Mariusz Kozlowski to fix unbalanced parentheses.
These changes are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-2.6-rcu.git rcu/next
------------------>
Frederic Weisbecker (2):
rcu: Stop chasing QS if another CPU did it for us
rcu: Keep gpnum and completed fields synchronized
Lai Jiangshan (2):
rcu,cleanup: move synchronize_sched_expedited() out of sched.c
rcu,cleanup: simplify the code when cpu is dying
Mariusz Kozlowski (1):
rculist: fix borked __list_for_each_rcu() macro
Paul E. McKenney (14):
rcu: add priority-inversion testing to rcutorture
rcu: move TINY_RCU from softirq to kthread
rcu: priority boosting for TINY_PREEMPT_RCU
rcu: add tracing for TINY_RCU and TINY_PREEMPT_RCU
rcu: document TINY_RCU and TINY_PREEMPT_RCU tracing.
rcu: Distinguish between boosting and boosted
rcu: get rid of obsolete "classic" names in TREE_RCU tracing
rcu: update documentation/comments for Lai's adoption patch
rcu: fix race condition in synchronize_sched_expedited()
rcu: Make synchronize_srcu_expedited() fast if running readers
rcu: fine-tune grace-period begin/end checks
rcu: limit rcu_node leaf-level fanout
rcu: reduce __call_rcu()-induced contention on rcu_node structures
rcu: remove unused __list_for_each_rcu() macro
Tejun Heo (1):
rcu: increase synchronize_sched_expedited() batching
