I applied this on top of net-next, from:
git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git (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.
