Right, I see the same soft lockup. Interestingly I cannot trigger it
with the rht test code. I can only trigger it with your Netlink socket
creation stress test. It is definitely related to the deferred worker,
when I disable growing, then the bug disappears.

Yes, when I disable expansion, the soft lockup also disappears too.

I have found the last remaining race and can now run your test
program successfully in an endless loop.

I will resubmit a v2 of this series.

Thanks! Once I receive your updates, I will test them again.
