When compiling the cgroup selftests with the following command:
make -C tools/testing/selftests/cgroup/
the compiler complains as below:
test_cpu.c: In function ‘test_cpucg_nice’:
test_cpu.c:284:39: error: incompatible type for argument 2 of ‘hog_cpus_timed’
284 | hog_cpus_timed(cpucg, param);
| ^~~~~
| |
| struct cpu_hog_func_param
test_cpu.c:132:53: note: expected ‘void *’ but argument is of type ‘struct cpu_hog_func_param’
132 | static int hog_cpus_timed(const char *cgroup, void *arg)
| ~~~~~~^~~
Fix it by passing the address of param to hog_cpus_timed().
