Hi Peter,
I posted the new v5 patch with the one-line fix at
https://lore.kernel.org/all/20221026233839.1934419-1-surenb@google.com.
I didn't notice the issue because that path is only used when
CONFIG_IRQ_TIME_ACCOUNTING is enabled, which I haven't tested :(
Please try picking it now. I think nothing should fail this time
around (famous last words).
Thanks,
Suren.
