Date: Wed, 04 Nov 2026 01:53:25 +0000 [thread overview]
Message-ID: <sashiko-outbox-196397@kernel.org> (raw)
In-Reply-To: <20261103015238.3780910-8-sashal@kernel.org>
> perf_lopwr_cb() is called from the noinstr acpi_idle_do_entry(). The
> x86 implementation is __always_inline, but the empty fallback is a
> plain static inline function, which the compiler won't inline into
> noinstr code when building with code coverage instrumentation:
>
> vmlinux.o: warning: objtool: acpi_idle_do_entry+0x4: call to perf_lopwr_cb() leaves .noinstr.text section
>
> Make the stub __always_inline as well.
