+Subject: os/inputthread: Force unlock when stopping thread.
+Patch-Mainline: To be upstreamed
+References: bnc#1062977
+
+The inputthread is kept locked all the time while X server's VT is not active.
+If the X server is terminated while not active, it will be stuck forever in
+InputThreadFini waiting for the thread to join, but it wouldn't because it is
+locked.
+---
+This fixes the X server termination while its VT is not active. I think it
+should be safe to force unlock it from InputThreadFini - X server is
+terminating and nothing else should race there, but I am not completely sure.
