I applied this on top of net-next, from:

 (master branch)

and got this compile error:

kernel/trace/trace_events_filter.c: In function ‘emit_cond’:
kernel/trace/trace_events_filter.c:1361:36: error: ‘__bpf_call_base’ undeclared (first use in this function)
kernel/trace/trace_events_filter.c:1361:36: note: each undeclared identifier is reported only once for each function it appears in
kernel/trace/trace_events_filter.c: In function ‘filter_gen_bpf’:
kernel/trace/trace_events_filter.c:1622:2: error: implicit declaration of function ‘bpf_int_jit_compile’ [-Werror=implicit-function-declaration]

Config attached.
