No, if you kick me little I do it:-)

git clone -o mainline --no-checkout \
   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git ~/linux/
cd ~/linux/
git remote add -t master stable \
   https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
git checkout --detach v6.8

cd ~/linux/

git cherry-pick
--no-commit   52f96cd135b160d44db4cb62a5b614b3bca20fbc]

Is this right way ?

	Regards
			Dan
