It would be great to backport those 5 mentioned to 6.11.y.

Stable kernels last until the next release happens, like has been happening for 15+ years now, nothing new here :) If you wish to have patches backported to stable kernels, please read https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html for how to do this properly. thanks, greg k-h
