Hey Daniel, The script knows how to read stable tags :) It tested out 4.9 because the commit also has a fixes tag pointing to d3862e44daa7 ("dma-buf/sw-sync: Fix locking around sync_timeline lists."), which was backported to 4.9. Should this not be backported to 4.9, even though the commit it fixes is there? -- Thanks, Sasha
