Please look at the git history to find out what the normal subject

Please *succinctly* explain what the bug is, assuming the person
reading the description can also read the code. Or should I say 
ask your LLM to do it, 'cause I really doubt you wrote this bloviated

You must provide an appropriate Fixes tag for fixes in the Linux kernel.
