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.
Yeah, I've observed this problem before, so thanks for fixing.
It's CONFIG_KFENCE_NUM_OBJECTS (not "DYNAMIC") - please fix in all patches.
Sorry for this mistake, I will check it in all patches.
