I feel a bit uncomfortable to send a mix of 3 patches to fix one bug.

Could you instead send pure fix (fixing dst leak) for net tree ?

Then, when fix is incorporated in net-next, send the cleanups ?

This also clashes with this pending work, so it would ease things if you
can respin the cleanups for net-next

Thanks !
