This series is to fix UAF when running kfence test case test_gfpzero,
which is time costly. This UAF bug can be easily triggered by setting
CONFIG_KFENCE_DYNAMIC_OBJECTS = 65535. Furthermore, some optimization
for kunit tests has been done.

  kunit: fix UAF when run kfence test case test_gfpzero
  kunit: make kunit_test_timeout compatible with comment
  kfence: test: try to avoid test_gfpzero trigger rcu_stall
