I had hoped we could maybe narrow down the range to bisect by compile... 
As it stands, testing each Debian kernel image released since 5.15.2 
already requires a bisect approach so you indeed have your work cut out 
for you.

Let me know what you find - the list of commits in mm/ is too huge to 
contemplate in its entirety but might be easier to digest from one 
release to another.

Cheers,

	Michael
