[PATCH RFC v2 net-next 05/16] bpf: introduce syscall(BPF, ...) and BPF maps

BPF syscall is a demux for different BPF releated commands. 'maps' is a generic storage of different types for sharing data between kernel and userspace. The maps can be created from user space via BPF syscall: - create a map with given type and attributes fd = bpf_map_create(map_type, struct n
