I'm definitely not happy with the fix but the breakage was unintentional and given that it was done for a W=1 warning, the patch was low priority and I felt that users that do error injection to stress failure paths at least had some value. If I was fixing something important, I would feel differently and we've slammed patches before that fixed warnings while introducing worse problems. I'm still hoping that BTF gets fixed because it's the right thing to do. -- Mel Gorman SUSE Labs
