That's v6.15. At time of writing v6.16-rc3 was out. At a minimum I would
expect new functionality targeting the next kernel to be based on -rc2
of the previous kernel.

It might be ok if the conflicts are low, but going forward do move your
baseline to at least -rc2 if not later.

This highlights that CXL needs a
Documentation/process/maintainer-handbooks.rst entry to detail
expectations like this.
