Hm, now I get:

../kernel/trace/trace.c: In function 'tracing_set_tracer':
../kernel/trace/trace.c:4850:3: error: implicit declaration of function 'free_snapshot' [-Werror=implicit-function-declaration]
   free_snapshot(tr);
   ^
../kernel/trace/trace.c:4856:3: error: implicit declaration of function 'alloc_snapshot' [-Werror=implicit-function-declaration]
   ret = alloc_snapshot(tr);
   ^
