[bug#70962] [PATCH 14/14] gnu: linux-libre-with-bpf: Deprecate in favor of linux-libre. |
Date: |

The kernel has progressively enabled the BPF settings, to the point where
having a separate kernel for it makes little sense, so repatriate the few
non-default BPF-related configs to our main kernel.
* gnu/packages/linux.scm (%bpf-extra-linux-options): Delete variable.
(default-extra-linux-options): Enable CONFIG_NET_CLS_BPF and
CONFIG_NET_ACT_BPF. CONFIG_IKHEADERS is dropped as it adds 4 MiB to the
kernel image and appears somewhat redundant with BTF debug info.
(linux-libre-with-bpf): Deprecate to linux-libre.
