Happy to answer why!

It was proposed for 5.15, but dropped due to build failures:

	https://lore.kernel.org/all/202202131427.SK7CctaU-lkp@intel.com/

The missing functions were later brought to the 5.15 tree via:

	https://lore.kernel.org/all/20230601131937.674646135@linuxfoundation.org/

At this point, Greg's current backport of the commit in question was
successful.
