Apparently it wasn't.

However, I've an LKP success report for f97634611408 (prior to pushing it 
to for-next, I always wait for LKP).

Why LKP didn't catch it despite claiming it built with x86_64_allyesconfig 
(successfully)?? Did LKP not build the tree??

I've pulled the commit from for-next until the problem is resolved to not 
keep breaking builds. Joshua, could you please take a look at it.
