Subject: [PATCH 6.1.y 2/6] PCI: Free saved list without holding pci_bus_sem
Date: Tue, 14 Jul 2026 22:45:55 -0400 [thread overview]
Message-ID: <20260715024559.106836-2-sashal@kernel.org> (raw)
In-Reply-To: <20260715024559.106836-1-sashal@kernel.org>
From: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>
[ Upstream commit 1d8a0506f69895b7cfd9d5c4546761c508231a8a ]
Freeing the saved list does not require holding pci_bus_sem, so the
critical section can be made shorter.
