Unless I stuffed something up, it looks like only about 2% of these
"Fixes: " commits were for existing defects in earlier non-rc releases.

$ git log --grep="^Fixes:" --no-merges --pretty=oneline v5.18..v5.19 | wc -l
2531

$ git log --grep="^Fixes:" --no-merges --pretty=oneline v5.18..v5.19 | \
  cut -f1 -d" " | \
  while read line ; do \
    echo -n "---> $line" ; \
    echo ":$(git rev-list --max-count=2 v5.18..$line | wc -l)" ; \
  done | \
  grep ":1" | wc -l
