Package: linux-headers-4.2.0-trunk-all Severity: normal Tags: patch For unknown (stupid) reasons, flush_workqueue symbol has been declared as GPL only. There is a pending fix in the kernel git, please cherry-pick it. The resolution blocks #796372.
commit 1dadafa86a779884f14a6e7a3ddde1a57b0a0a65 Author: Tim Gardner <tim.gard...@canonical.com> Date: Tue Aug 4 11:26:04 2015 -0600 workqueue: Make flush_workqueue() available again to non GPL modules 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.
