Yeah, apologiues for not getting back to you earlier.  Between travel
and the holidays, I didn't have time to process patches for the merge
window which just closed, so I'm not catching up on the backlog.

In any case, Eric's commit is in 6.14-rc1, so you should see the flex
array warnings from the ext4 checksum inline function.
