Subject: [PATCH tip/core/rcu 0/6] Idle entry/exit changes for 3.13
Date: Tue, 24 Sep 2013 18:49:55 -0700 [thread overview]
Message-ID: <20130925014954.GA32109@linux.vnet.ibm.com> (raw)
Hello!
This series updates RCU's idle entry/exit processing:
1. Remove redundant code from rcu_cleanup_after_idle().
2. Throttle rcu_try_advance_all_cbs() execution to avoid kbuild
slowdowns.
3. Throttle non-lazy-callback-induced invoke_rcu_core() invocations.
4. Add primitive to determine whether it is safe to enter an RCU
read-side critical section.
5. Upgrade EXPORT_SYMBOL() to EXPORT_SYMBOL_GPL().
6. Change rcu_is_cpu_idle() function to __rcu_is_watching() for
naming consistency.
Thanx, Paul
