It should be fine. It's more like I just didn't like the idea of it. Workqueue execution path isn't really light enough for an addition of single smp_rmb() per work item execution makes any noticeable difference. No harm in measuring perf delta but I'm highly skeptical that there will be any difference which can be measured.
