When using uprobes with BTF resolve support, enum is not a recognized type and this makes the resolve function not return the right value:

apiVersion: cilium.io/v1alpha1
kind: TracingPolicy
metadata:
  name: "uprobe-example"
spec:
  uprobes:
  - path: "/home/litios/testbin"

    - "testfunc"
    args:
    - index: 0
      type: "uint64"
      btfType: "test_struct"
      resolve: "testenum"
    selectors:
    - matchActions:
      - action: Post  

#include <stdint.h>

enum test_enum {
    TEST_ENUM_0 = 0,
    TEST_ENUM_1 = 1,
    TEST_ENUM_2 = 2,
};

struct test_struct {
    int fd;
    char* test;
    enum test_enum testenum;
};

int testfunc(struct test_struct s) {
    return s.testenum;
}

void main() {
    struct test_struct ctx;
    ctx.fd = 1;
    ctx.test = "dada";
    ctx.testenum = TEST_ENUM_1;
    testfunc(ctx);
}

Describe the feature you would like

It looks like enum is not being resolved properly with uprobes resolve (BTF).

(@tdaudi provided a solution that seems to work already! PR pending)
