Subject: [PATCH tip/core/rcu 0/2] Callback-offloading changes for 3.17
Date: Mon, 7 Jul 2014 15:48:41 -0700 [thread overview]
Message-ID: <20140707224841.GA10101@linux.vnet.ibm.com> (raw)
Hello!
This series provides a couple of callback-offloading changes:
1. Parallelize and economize NOCB kthread wakeups to better handle
cases where callback offloading is used on workloads that have
many context switches and thus many grace periods.
2. Don't offload callbacks for a given CPU unless it has been
explicitly requested for that CPU, either directly at build
time or boot time, or indirectly at boot time due to that
CPU being a nohz_full CPU.
Thanx, Paul
