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?
