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_NUM_OBJECTS = 65535. Furthermore, some optimization for kunit tests has been done.

I was able to reproduce the error you described and can confirm that I didn't see the UAF after applying your patches.
