Andres Rodriguez 03c0c5f664 dma-buf: avoid scheduling on fence status query v2 ... When a timeout of zero is specified, the caller is only interested in the fence status. In the current implementation, dma_fence_default_wait will always call schedule_timeout() at least once for an unsignaled fence. This adds a significant overhead to a fence status query. Avoid this overhead by returning early if a zero timeout is specified. v2: move early return after enable_signaling Signed-off-by: Andres Rodriguez <andresx7@gmail.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170426144620.3560-1-andresx7@gmail.com		2017-04-27 16:56:10 -03:00
