On linux stable-rc 5.15 x86 and i386 builds failed due to below error [1]
with config [2].

The finding is when kunit config is enabled the builds pass.
CONFIG_KUNIT=y

But with CONFIG_KUNIT not set the builds failed.

x86_64-linux-gnu-ld: mm/kfence/core.o: in function `__kfence_alloc':
core.c:(.text+0x901): undefined reference to `filter_irq_stacks'
make[1]: *** [/builds/linux/Makefile:1183: vmlinux] Error 1

Reported-by: Linux Kernel Functional Testing <lkft@linaro.org>

I see these three commits, I will bisect and get back to you

2f222c87ceb4 kfence: limit currently covered allocations when pool nearly full
e25487912879 kfence: move saving stack trace of allocations into
__kfence_alloc()
d99355395380 kfence: count unexpectedly skipped allocations
