Actually 'eventually succeed' is not even quite right There are situations where a driver object will be created and then destroyed during error unwind of the syscall eg via RDMA_REMOVE_ABORT_HWOBJ In which case, again, destroy must succeed or memory gets leaked and a WARN_ON trigger. This might be a problem still in the devx stuff :\ Jason
