From b6723c8da55af5309cf06e71a5228f3c02846c5a Mon Sep 17 00:00:00 2001 From: Monk Liu Date: Thu, 10 Mar 2016 12:14:44 +0800 Subject: drm/amdgpu: use ref to keep job alive this is to fix fatal page fault error that occured if: job is signaled/released after its timeout work is already put to the global queue (in this case the cancel_delayed_work will return false), which will lead to NX-protection error page fault during job_timeout_func.
