Have
I'm no longer able to build the samples with 'make M=samples/bpf'.
I get errors in task_fd_query_user.c like:
samples/bpf/task_fd_query_user.c:153:29: error: ‘PERF_EVENT_IOC_ENABLE’
undeclared.
Am I missing a dependancy?

raw_tracepoints are an eBPF alternative to standard tracepoints which
attach to a tracepoint without the perf layer being executed, making
them faster.
Since xdp_monitor is supposed to have as little impact on the system as
possible it is switched to using them by append raw_ to the SEC names.
