If there's a persistent error in the hypervisor, the SCSI warning for failed I/O can flood the kernel log and max out CPU utilization, preventing troubleshooting from the VM side. Ratelimit the warning so it doesn't DoS the VM.

I just remembered that we should wait for Linus to tag the rc before sending backports, so apologies for sending this (and its 6.1 and 6.12 friends) out before rc1 was tagged.
Why was this not tagged for stable in the first place?
thanks,
