I've pulled Linus' tree yesterday, booted, all fine - just now it was the 
first time I saw a similar WARNING on my box (running -rc kernels 
for a few months now), see below.

Is this related to the WARNING in #13666?
I'm pretty sure the kernel already includes the patches you 
mentioned, "git show" said "b592972493c38665efd7d429a01b23fcb21e331a". 
Also, I just pulled again and mm/ was not touched any more.

Or maybe this is related to ext4 stuff? (I just mounted an ext4 partition 
when this WARNING happened). Full dmesg & .config:

Thanks,
Christian.
