However we are facing a new situation: in test robot POV, IMHO there
are values to test exactly the same tree as the patch submitter.
Otherwise the robot risks

- false negative: failing to apply and test some patches
- false positive: sending wrong bug reports due to guessed wrong base tree

Wouldn't the important part here be the git hash, rather than the tree?
 If you have the same hash then it by definition is the same contents?

Yes. Sorry for the partial wording! We should be talking about the
same thing: the hash of the tree object. The commit SHA1 will also
do the work.

Thanks,
