Subject: kernel/smp.c:on_each_cpu_cond(): fix warning in fallback path
From: Sasha Levin <[email protected]>
commit 618fde872163e782183ce574c77f1123e2be8887 upstream.
The rarely-executed memry-allocation-failed callback path generates a
WARN_ON_ONCE() when smp_call_function_single() succeeds. Presumably
it's supposed to warn on failures.
