Without this fix, our e2e tests is having to be retested many times over and still doesn't guarantee success, when csi driver hits this issue, it doesn't seem to get out of it easily.

There is no impact on functionality. But there are too many of these errors.

snapshot controller failed to update ...xxxxx
the object has been modified; please apply your changes to the latest version and try again

    

almost every PR in oadp-operator have one or more of these "flake" errors that prevents our e2e from succeeding forcing a retest.
