# against K=13 (stable 6.19.14). Pinning to K=11 is a real regression

DESCRIPTION="Linux kernel: gentoo-sources base + curated pf-kernel patchset"
HOMEPAGE="https://pfkernel.natalenko.name/
https://dev.gentoo.org/~alicef/genpatches/"
# Vanilla 6.19 from kernel.org + Gentoo's genpatches (stable + non-stable)
# + our curated pf delta. The codeberg pf-kernel tarball is intentionally
# not fetched — its content is replaced by the much smaller curated
# patch in files/.
