test_kprobes: Fix implicit declaration error of test_kprobes
commit 63a4dc0a0bb0e9bfeb2c88ccda81abdde4cdd6b8 upstream.
If KPROBES_SANITY_TEST and ARCH_CORRECT_STACKTRACE_ON_KRETPROBE is enabled, but
STACKTRACE is not set. Build failed as below:
lib/test_kprobes.c: In function ‘stacktrace_return_handler’:
lib/test_kprobes.c:228:8: error: implicit declaration of function ‘stack_trace_save’; did you mean ‘stacktrace_driver’? [-Werror=implicit-function-declaration]
ret = stack_trace_save(stack_buf, STACK_BUF_SIZE, 0);
^~~~~~~~~~~~~~~~
stacktrace_driver
cc1: all warnings being treated as errors
scripts/Makefile.build:250: recipe for target 'lib/test_kprobes.o' failed
make[2]: *** [lib/test_kprobes.o] Error 1
To fix this error, Select STACKTRACE if ARCH_CORRECT_STACKTRACE_ON_KRETPROBE is enabled.
