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.
