Subject: Re: [PATCH v3 linux-trace 1/8] tracing: attach eBPF programs to tracepoints
 and syscalls

Hi, Alexei

Another suggestion on bpf syscall interface. Currently, BPF +
syscalls/kprobes depends on CONFIG_BPF_SYSCALL. In kernel used on
commercial products, CONFIG_BPF_SYSCALL is probably disabled, in this
case, bpf bytecode cannot be loaded to the kernel.

If we turn the functionality of BPF_SYSCALL into a loadable module, then
we can use it without any dependencies on the kernel. What about change
bpf syscall to a /dev node or /sys file which can be exported by a
kernel module?
