Introduce a new execobject.flag (EXEC_OBJECT_CAPTURE) that userspace may use to indicate that it wants the contents of this buffer preserved in the error state (/sys/class/drm/cardN/error) following a GPU hang involving this batch. Use this at your discretion, the contents of the error state. although compressed, are allocated with GFP_ATOMIC (i.e. limited) and kept for all eternity (until the error state is destroyed).
