* gpu: nvgpu: Store pending sema waitsAlex Waterman2016-12-19
| | | | | | | | | | | | | | | | | | | | | | | | | Store pending sema waits so that they can be explicitly handled when the driver dies. If the sema_wait is freed before the pending wait is either handled or canceled problems occur. Internally the sync_fence_wait_async() function uses the kernel timers. That uses a linked list of possible events. That means every so often the kernel iterates through this list. If the list node that is in the sync_fence_waiter struct is freed before it can be removed from the pending timers list then the kernel timers list can be corrupted. When the kernel then iterates through this list crashes and other related problems can happen.
