We want to change swap_state to wait indefinitely, but to do this swap_state should wait interruptibly. This requires propagating the error to each driver. All drivers have changes to deal with the clean up. In order to allow easy reverting, the commit that changes behavior is separate so someone only has to revert that for te...
