Hmmm, I can't see the results.  Did I miss anything?

	alx@debian:~$ uname -a
	Linux debian 6.15.0-seprintf-mm+ #5 SMP PREEMPT_DYNAMIC Mon Jul  7 19:16:40 CEST 2025 x86_64 GNU/Linux
	alx@debian:~$ cat /boot/config-6.15.0-seprintf-mm+ | grep KFENCE
	CONFIG_HAVE_ARCH_KFENCE=y
	CONFIG_KFENCE=y
	CONFIG_KFENCE_SAMPLE_INTERVAL=0
	CONFIG_KFENCE_NUM_OBJECTS=255
	# CONFIG_KFENCE_DEFERRABLE is not set
	# CONFIG_KFENCE_STATIC_KEYS is not set
	CONFIG_KFENCE_STRESS_TEST_FAULTS=0
	CONFIG_KFENCE_KUNIT_TEST=y
	alx@debian:~$ sudo dmesg | grep -i kfence
	alx@debian:~$ 

I see a lot of new stuff in dmesg, but nothing with 'kfence' in it.


Cheers,
Alex
