This highly unoptimized Q&D script will list patches not referenced anywhere
(will barf on filenames with spaces, but typically there are none such files ):

$1 = filoder to (recursively) check, i.e called from meta:  ./recipes-devtools

#!/bin/bash

findpatchesall=`find $1  -name '*.patch' -exec readlink -f {} \;`
findall=`find -L $1 -name '*.*' -not -name "*.patch" -exec readlink -f {} \;`

echo "patches: $findpatchesall"
echo "recipes: $findall"

# Go through all patches and see if any file references them
for patch in $findpatchesall
do
	#echo "checking $patch"
	patch_referenced="0"
	for file1 in $findall
	do
	patch1=`basename $patch`
	if [ -f "$file1" ]; then
		if grep -q $patch1 "$file1"; then
			#echo "referenced in: $file1"
			patch_referenced="1"
		fi
	fi
	done
	if [ "$patch_referenced" == "0" ]; then
		echo "*** $patch ***"
    fi
done
