Subject: [PATCH tip/core/rcu 0/6] Miscellaneous fixes for 4.7
Date: Tue, 12 Apr 2016 08:01:57 -0700 [thread overview]
Message-ID: <20160412150157.GA19367@linux.vnet.ibm.com> (raw)
Hello!
This series provides miscellaneous fixes for RCU:
1. Consolidate RCU's single-shot dumping of the ftrace buffer.
This is a bit widespread, so the upcoming documentation,
expedited-grace-period, and torture patchsets are also based
on this patch.
2. Awaken grace-period kthread at RCU CPU stall-warning time.
3. Move the FQS timeout farther into the future only if the current
wakeup actually resulted in an FQS scan.
4. Awaken grace-period kthread if too long since FQS.
5. Remove superfluous versions of rcu_read_lock_sched_held(),
courtesy of Boqun Feng.
6. Dump ftrace buffer when kicking grace-period kthread.
Thanx, Paul
