Description:

The CONFIG_BPF_SYSCALL needs to be enabled so that external callers can load BPF modules, such as the BCC project (provides libbcc.so, allowing Python to interface with BPF). https://github.com/iovisor/bcc

Specifically, while trying to make a good AUR project I found all samples failing (100%), it all leads back to being able to call this SYSCALL "bpf_prog_load()": http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/kernel/bpf/syscall.c#n590

This task depends upon
