This consists of simply storing the most recent deadline, and adding an ioctl to retrieve the deadline. This can be used in conjunction with the SET_DEADLINE ioctl on a fence fd for testing. Ie. create various sw_sync fences, merge them into a fence-array, set deadline on the fence-array and confirm that it is propagated properly to each fence. v2: Switch UABI to express deadline as u64 v3: More verbose UAPI docs, show how to convert from timespec v4: Better comments, track the soonest deadline, as a normal fence implementation would, return an error if no deadline set.
