To this rxe_skb_tx_dtor problem, I think I have posted a fix. Do you
make tests with it?
In general, syzbot can test patches for the bugs it reported:
https://github.com/google/syzkaller/blob/master/docs/syzbot.md#testing-patches

But syzbot hasn't (yet) managed to find a reproducer for that specific
issue, so there's no way for the tool to test the candidate fix.
Should I file an official commit to confirm if this problem is fixed or not?
