The call to flush_scheduled_work() in do_initcalls() is there to make sure all works queued to system_wq by initcalls finish before the init sections are dropped. However, the call doesn't make much sense at this point - there already are multiple different workqueues and different subsystems are free to create and use their own. Ordering requirements are and should be expressed explicitly. Drop the call to prepare for the deprecation and removal of flush_scheduled_work(). Andrew suggested adding sanity check where the workqueue code checks whether any pending or running work has the work function in the init text section. However, checking this for running works requires the worker to keep track of the current function being executed, and checking only the pending works will miss most cases. As a violation will almost always be caught by the usual page fault mechanism, I don't think it would be worthwhile to make the workqueue code track extra state just for this.

flush_scheduled_work() is deprecated and will be removed. Because kcapi uses fire-and-forget type works, it's impossible to flush each work explicitly. Create and use a dedicated workqueue instead. Please note that with recent workqueue changes, each workqueue doesn't reserve a lot of resources and using it as a flush domain is fine.

Currently, destroy_workqueue() makes the workqueue deny all new queueing by setting WQ_DYING and flushes the workqueue once before proceeding with destruction; however, there are cases where work items queue more related work items. Currently, such users need to explicitly flush the workqueue multiple times depending on the possible depth of such chained queueing. This patch updates the queueing path such that a work item can queue further work items on the same workqueue even when WQ_DYING is set. The flush on destruction is automatically retried until the workqueue is empty. This guarantees that the workqueue is empty on destruction while allowing chained queueing. The flush retry logic whines if it takes too many retries to drain the workqueue. Signed-off-by: NTejun Heo <tj@kernel.org> Cc: James Bottomley <James.Bottomley@HansenPartnership.com>

Running the annotate branch profiler on three boxes, including my main box that runs firefox, evolution, xchat, and is part of the distcc farm, showed this with the likelys in the workqueue code: correct incorrect % Function File Line ------- --------- - -------- ---- ---- 96 996253 99 wq_worker_sleeping workqueue.c 703 96 996247 99 wq_worker_waking_up workqueue.c 677 The likely()s in this case were assuming that WORKER_NOT_RUNNING will most likely be false. But this is not the case. The reason is (and shown by adding trace_printks and testing it) that most of the time WORKER_PREP is set. In worker_thread() we have: worker_clr_flags(worker, WORKER_PREP); [ do work stuff ] worker_set_flags(worker, WORKER_PREP, false); (that 'false' means not to wake up an idle worker) The wq_worker_sleeping() is called from schedule when a worker thread is putting itself to sleep. Which happens most of the time outside of that [ do work stuff ]. The wq_worker_waking_up is called by the wakeup worker code, which is also callod outside that [ do work stuff ]. Thus, the likely and unlikely used by those two functions are actually backwards. Remove the annotation and let gcc figure it out.
