Hi, This series focus on mounting (or not mounting) tracefs with bpftool. First patch makes bpftool attempt to mount tracefs if tracefs is not found when running "bpftool prog tracelog".
Second patch adds an option to bpftool to prevent it from attempting to mount any file system (tracefs or bpffs), in case this behaviour is undesirable for some users.
