Reviewed-by: Peter Xu <pet...@redhat.com> Thanks, Jan. The "non-cosmetic" part of clearing of those entries (e.g. including when the entries were not setup correctly rather than masked) was never really implemented and that task has been on my todo list for quite a while but with a very low priority (low enough to sink...). I hope I didn't overlook its importance since AFAICT general OSs should hardly trigger those paths and so far I don't see it a very big issue. Regards, -- Peter Xu
