How to have a 'bpf.sig_enforce' command line arg in kernel/bpf/syscall.c ?

[Arnaldo Carvalho de Melo]

If I use:

module_param_named(bpf.sig_enforce, sig_enforce, bool_enable_only, 0644);

It explodes and if I do as before:

module_param(sig_enforce, sig_enforce, bool_enable_only, 0644);

Then it ends up as 'syscall.sig_enforce'.

The closest I got so far was:

    kbuild: define KBUILD_MODNAME even if multiple modules share objects


Is there some way to set that modname var to 'bpf' in
kernel/bpf/syscall.c?
