  [Regression Potential]
-  * Regression potential should be low, as we're now updating the VSI using the ID stored in the VF pointer
-  * Regressions could arise from issues in VF creation or reset, as that would corrupt the new VSI pointer
-  * Patch was validated and tested in a production environment

- [Other]
-  * Fix was introduced in v5.4-rc1, so all previous kernels are affected
