The 'duration' variable is referenced in the CHECK() macro, and there are
some uses of the macro before 'duration' is set. The clang compiler
(validly) complains about this.
Sample error:
.../selftests/bpf/prog_tests/fexit_test.c:23:6: warning: variable 'duration' is uninitialized when used here [-Wuninitialized]
if (CHECK(err, "prog_load sched cls", "err %d errno %d\n", err, errno))
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.../selftests/bpf/test_progs.h:134:25: note: expanded from macro 'CHECK'

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
_CHECK(condition, tag, duration, format)
