It looks like this patch had been merged into linux-next but the "[PATCH 1/2]
kunit: support failure from dynamic analysis tools" did not. Hence, it caused a
compiling failure.
lib/ubsan.c: In function ‘ubsan_prologue’:
lib/ubsan.c:141:2: error: implicit declaration of function
‘kunit_fail_current_test’; did you mean ‘kunit_init_test’?
[-Werror=implicit-function-declaration]
kunit_fail_current_test();
^~~~~~~~~~~~~~~~~~~~~~~
kunit_init_test
