Pull workqueue updates from Tejun Heo: "rcu_work addition and a couple trivial changes" * 'for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: remove the comment about the old manager_arb mutex workqueue: fix the comments of nr_idle fs/aio: Use rcu_work instead of explicit rcu and work item cgroup: Use rcu_work instead of explicit rcu and work item RCU, workqueue: Implement rcu_work

workqueue: remove the comment about the old manager_arb mutex

2018-03-20T20:01:45Z

The manager_arb mutex doesn't exist any more. Signed-off-by: Lai Jiangshan Signed-off-by: Tejun Heo

workqueue: fix the comments of nr_idle

2018-03-20T20:01:36Z

Since the worker rebinding behavior was refactored, there is no idle worker off the idle_list now. The comment is outdated and can be just removed. It also groups nr_workers and nr_idle together. Signed-off-by: Lai Jiangshan Signed-off-by: Tejun Heo

RCU, workqueue: Implement rcu_work

2018-03-19T17:12:03Z

There are cases where RCU callback needs to be bounced to a sleepable context. This is currently done by the RCU callback queueing a work item, which can be cumbersome to write and confusing to read. This patch introduces rcu_work, a workqueue work variant which gets executed after a RCU grace period, and converts the open coded bouncing in fs/aio and kernel/cgroup. v3: Dropped queue_rcu_work_on(). Documented rcu grace period behavior after queue_rcu_work(). v2: Use rcu_barrier() instead of synchronize_rcu() to wait for completion of previously queued rcu callback as per Paul.

workqueue: remove unused cancel_work()

2018-03-13T20:37:42Z

Found this by accident. There are no usages of bare cancel_work() in current kernel source. Signed-off-by: Stephen Hemminger Signed-off-by: Tejun Heo

workqueue: use put_device() instead of kfree()

2018-03-13T20:26:03Z

Never directly free @dev after calling device_register(), even if it returned an error! Always use put_device() to give up the reference initialized in this function instead. Signed-off-by: Arvind Yadav Signed-off-by: Tejun Heo

sched/isolation: Isolate workqueues when "nohz_full=" is set

2018-02-21T08:49:08Z

As we prepare for offloading the residual 1hz scheduler ticks to workqueue, let's affine those to housekeepers so that they don't interrupt the CPUs that don't want to be disturbed.
