From 217877d046414878126e5c8013162e3b7edc774c Mon Sep 17 00:00:00 2001 From: Tony Ambardar Date: Wed, 22 Jul 2020 06:28:06 -0700 Subject: [PATCH] base-files: mount bpffs at boot Explicitly mount the BPF filesystem if available. This is used for pinning eBPF programs and maps, making them accessible to other eBPF programs or from userspace with the help of libbpf or bpftool.
