OK, thanks for the clarification. This is a known problem. Have a look
at I think we consider that one to 0158115f702b ("memcg, kmem: deprecate
kmem.limit_in_bytes"). We are reporting the deprecated and to-be removed
status since 2019 without any actual report sugested by the kernel
message. Maybe we should try and remove it and see whether that prompts
some pushback.
