Siyuan:
You are correct. CleanCertsFromDb is dedicated for NV time based variable.
The change is just to cooperate DeleteCertsFromDb interface change.
Thanks & Best regards

Subject: RE: [PATCH 2/2] SecurityPkg: AuthVariableLib: Add new cert database
for volatile time based Auth variable
Hi, Chao
The changes for CleanCertsFromDb() function seems unnecessary, Certdbv is a
volatile variable so it doesn't need clean up logic on system crash. Other
parts are good for me.
