# 6.16 is a non-LTS kernel that reached end-of-life upstream (linux-stable
# stopped at 6.16.12). genpatches' last bundle for this branch (-15)
# tracks stable through 6.16.12 — full coverage. ::gentoo no longer
# ships gentoo-sources-6.16.X, but alicef's release tarballs remain
# available on dev.gentoo.org, which is what this ebuild fetches.
