Subject: Re: [PATCH v5 2/2] LSM: add SafeSetID module that gates setid calls

FWIW, I've now done a manual test of this LSMs functionality on a
Linux VM built from the next-general branch. Adding policies, policy
enforcement by the LSM, and flushing policies all worked as intended.
So there hopefully won't be any more surprises.
