Subject: workqueue: Make flush_workqueue() available again to non GPL modules
From: Tim Gardner <tim.gardner@xxxxxxxxxxxxx>
commit 1dadafa86a779884f14a6e7a3ddde1a57b0a0a65 upstream.
Commit 37b1ef31a568fc02e53587620226e5f3c66454c8 ("workqueue: move
flush_scheduled_work() to workqueue.h") moved the exported non GPL
flush_scheduled_work() from a function to an inline wrapper.
Unfortunately, it directly calls flush_workqueue() which is a GPL function.
This has the effect of changing the licensing requirement for this function
and makes it unavailable to non GPL modules.
See commit ad7b1f841f8a54c6d61ff181451f55b68175e15a ("workqueue: Make
schedule_work() available again to non GPL modules") for precedent.
