Hi @umagnus. Thanks for your PR.

I'm waiting for a kubernetes-csi member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@xing-yang do you know where is the source of this generated file? it's a Chinese quote char which needs to be fixed since it would fail our yamllint check test.

[umagnus]

I think it's generated by client/apis/volumesnapshot/v1/types.go, and also fix it

[umagnus]

seems it's not source file, vendor will fail the test
