$?
The names of all the prerequisites that are newer than the target, with spaces between them.
While two `$?' was passed to bash in a line, it caused above failure,
drop a duplicated one could workaround the issue.

Added explanation of the `k8s:conversion-gen-external-types` comment
tag.
Added explanation of how the developer can selectively override the
generated conversion functions.
Also updated description in Makefile.generated_files.
One can run:
make generated_files UPDATE_API_KNOWN_VIOLATIONS=true
to update the checked-in known API violation exceptions list.
Also updated README and the error message on how to resolve the
failure.
Automatic merge from submit-queue (batch tested with PRs 66341, 66405, 66403, 66264, 66447). If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>.
Move api rules list under api-approvers-owned package
Additions to this list should be rare and carefully reviewed
```release-note
NONE
```
check in existing API rule violations;
the Make rule fails if generated violation report differs from the
checked-in violation file and prints error message;
add documentation.
Don't revert, change boundingdirs in Makefile for deepcopy-gen
manually fix pkg/client/clientset_generated/clientset/typed/core/v1/pod_expansion.go because external policy types are moved now
