[PATCH bpf-next v3 4/5] tools: sync bpf.h

Matt Mullins
2019-04-19T21:05:20Z

This adds BPF_PROG_TYPE_RAW_TRACEPOINT_WRITABLE, and fixes up the

error: enumeration value ‘BPF_PROG_TYPE_RAW_TRACEPOINT_WRITABLE’ not handled in switch [-Werror=switch-enum]

build errors it would otherwise cause in libbpf.
