Subject: [PATCH 6.12.y 2/2] panic: flatten nmi_panic control flow
Date: Tue, 10 Nov 2026 13:39:11 -0500 [thread overview]
Message-ID: <20261110183723.3255298-2-sashal@kernel.org> (raw)
In-Reply-To: <20261110183723.3255298-1-sashal@kernel.org>
From: Bradley Morgan <brads@mainlining.org>
[ Upstream commit 75eb687ff2bcec9fba31bbe266e5f91e5c283efe ]
panic() is __noreturn, so the else after panic_try_start() is dead. Drop
it so the force_cpu path can be added cleanly on top.
