I'm curious why this is only showing up as failing on next-next.
Let's see if it fails on the ext4.git tree.
>From the bisect logs syzbot is able to repro on all of v5.x and
v4.20.0. However, I'm not able to repro it using kvm with either
v5.6-rc4 or the tip of the ext4 git tree. So let's see what syzbot
can do with the tip of the dev tree.
