Well yes, the followup patch (https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/xfs-support-cow-in-fsdax-mode-fix.patch) will most definitely be folded. Can you suggest how this can be communicated to the robot in order to suppress this notification? A Fixes: won't work, as neither of these patches have yet been promoted to a "stable" state. Their hashes will change.
