What kind of environment is this?
Havign that inode list corruption makes it smell a *bit* like the
crazy memory corruption that we saw with the google cloud instances,
but that would only happen wif you actually use VIRTIO for your
environment?
Do you see the same issue with plain v6.0-rc1?

Yeah, it's not enough to just enable the VIRTIO support, it actually
needs to run in a virt environment, and with a hypervisor that gets
confused by the virtio changes.

Ok, so definitely not related to the google cloud issue we had in rc1.

This is a physical hardware db410c device.

Nope. I do not notice reported BUG on v6.0-rc1.

Is it reliable enough that you could possibly do a bisection between
v6.0-rc1 and next-20220816?
