workqueue: Make schedule_work() available again to non GPL modules (ad7b1f84) · Commits · 戴 / test

Commit ("workqueue: inline trivial wrappers") changed schedule_work() and schedule_delayed_work() to inline wrappers, but these rely on some symbols that are EXPORT_SYMBOL_GPL, while the original functions were EXPORT_SYMBOL. This has the effect of changing the licensing requirement for these functions and making them unavailable to non GPL modules. Make them available again by removing the restriction on the required symbols. Signed-off-by:
