Failed test got passed after enabling /proc/kallsyms, using:
echo 0  > /proc/sys/kernel/kptr_restrict

Following is the report of ftracetest on Linux v6.4.0-rc7 (with/without eventfs):
# of passed:  68
# of failed:  0
# of unresolved:  6
# of untested:  0
# of unsupported:  45
# of xfailed:  0
# of undefined(test bug):  0 

If lockdep is enabled getting same warning as reported by 'kernel test robot' for v3 09/10:
