Dear Ilya,
thanks for the quick response. Good to know that it is harmless.
It is very irritating though. I did maintenance some time ago adding lots of new disks and restarting the MDSses and the system got a bit stressed. These messages started to run over the root console with such a frequency that I could hardly type commands and read output.
Would be great if you could push this patch to the latest stable kernel.
Thanks and best regards,

Hi Frank,
It should be harmless. This warning was removed in kernel 5.11.
Jeff, we should probably push that patch to stable kernels.
Thanks,
Ilya
