Hi,
since updating the bullseye kernel to 5.10.179-5, we get the following
kernel WARNING (and so a tainted kernel) while running under vmware ESX:

This sounds like the issue described in
https://lore.kernel.org/lkml/2023081511-easing-exerciser-c356@gregkh/
Could you please follow up and include the fix in case its not in the
next kernel pointrelease?
Thanks,
