 My interpretation is that 2640e819474f (i.e. a commit not present in the 
 Debian kernels yet) is needed to make this problem considerably more 
 likely to occur. So I'd expect that yes 6.16 has a problem, but it 
 doesn't trigger often.

 Applying a commit fast to the Debian kernel also has the downside to 
 skip over a maturation process. While I would consider Rafael's 
 judgement a strong hint and the patch simple enough to consider the 
 change safe enough, there is a good reason the Greg Kroah-Hartman sends 
 out the patches he queued for the upcoming stable release to the mailing 
 list. There is an armada of people and bots that review and do build and 
 runtime tests that is very valuable. 
  
 Best regards 
 Uwe
