If a kernel enqueue fails the runtime will immediately try and clean it up. However, if it has any dependencies or users the cleanup will be skipped. This can cause the dependencies to stay alive and leak. These changes forces a full sub-graph cleanup of the command if enqueuing failed. Additionally, sub-graph cleanup is changed to account for failed kernel enqueues and will remove the failed command from its leaves. Signed-off-by: Steffen Larsen <[email protected]>

This commit adds a new strategy for cleaning up failed commands, namely to walk up the failed commands and its users and replace them by empty commands. This preserves the structure of the graph while replacing failed state. Signed-off-by: Steffen Larsen <[email protected]>
