Subject: [PATCH tip/core/rcu 0/9] v2 Fixes for 3.12
Date: Mon, 19 Aug 2013 19:41:48 -0700 [thread overview]
Message-ID: <20130820024148.GA30283@linux.vnet.ibm.com> (raw)
Hello!
This series contains a number of miscellaneous fixes:
1. Switch to expedited grace periods during hibernation and
suspend/resume operations (courtesy of Borislav Petkov and
Bjørn Mork).
2. Make RCU debugobjects fixup actions leak callbacks rather than
risking corrupting the callback lists.
3. Propagate above callback leaking to debugobjects's callers.
4. Make call_rcu() leak callbacks when debugobjects indicates an error.
5. Avoid needless self-wakeups from the grace-period kthreads.
6. Make list_first_or_null_rcu() use list_entry_rcu() (courtesy of
Tejun Heo).
7. Fix irq_work_queue() build error for TREE_PREEMPT_RCU for some
configurations (courtesy of James Hogan).
8. Simplify _rcu_barrier() processing per Linus Torvalds feedback.
9. Avoid signed-overflow undefined behavior in time_after() and friends.
Changes since v1 (https://lkml.org/lkml/2013/8/17/106):
o Merge v1 patches 1, 2, and 6 into the new patch 1.
o Apply other review comments from Josh Triplett.
Thanx, Paul
